Math
Ready to sharpen your math skills with quick quizzes you can finish in about five minutes? This collection of math quizzes covers the everyday arithmetic and geometry that show up in real life, from splitting a bill to reading a recipe.
What These Math Quizzes Cover
These math quizzes cover the core skills you use again and again, from working with decimals and fractions to rounding numbers and basic geometry. You can line up decimals in sums like 0.49 + 0.91 = 1.40, reduce fractions such as 6/18 to 1/3, and round a value like 1,843 to 1,800.
There is plenty more to pick from. Geometry sets name angles and polygons and build perimeter from a simple square. The order of operations quizzes drill the right sequence in problems like 5 + 3 x (4 + 2), while the units of measurement sets turn 4.0 kilograms into pounds. Divisibility quizzes round things out with quick checks for whether a number splits evenly.
Visual Math with a Picture Quiz
Not every quiz is bare numbers. One fractions set shows a group of colorful butterflies and asks what part of the whole a single color makes up. Because you can count the answer right there on screen, the idea of a numerator and denominator clicks in a way plain digits sometimes miss.
The Math Shortcuts Worth Memorizing
A lot of math comes down to patterns that save real time. The test for 9 feels like a trick: add up a number's digits, and if that sum divides by 9, the whole number does too. Polygon names follow Greek prefixes, so penta (five) gives you the pentagon and hexa (six) gives the hexagon.
A few results catch people off guard. Dividing by a number smaller than one makes the answer bigger, which is why 3.50 / 0.05 climbs all the way to 70. Spotting these patterns is what lets you estimate in your head instead of reaching for a calculator.

Decimals
You're splitting a bill, lining up the numbers, and suddenly the decimal points will not behave. Working with decimals comes down to a few reliable habits, and these quizzes build them until adding, subtracting, multiplying, and dividing feel automatic. Adding, Subtracting, Multiplying, and Dividing Decimals The sets cover the full toolkit. You will line up place values to add pairs like 0.49 + 0.91 = 1.40, borrow your way through differences like 8.7 - 6.6 = 2.1, count decimal places to land 2.0 x 0.8 = 1.6, and shift the point to solve divisions like 1.8 / 0.4 = 4.5. Other quizzes flip decimals into percentages and back, turning 0.65 into 65% and 12% into 0.12. The whole skill rests on tracking the decimal point carefully, and the sets step up gradually from tenths to thousandths so nothing feels like a leap. The Surprises Hiding in Decimal Math A few results catch people off guard. Dividing by a number smaller than one actually makes the answer bigger, which is why 3.50 / 0.05 lands all the way up at 70. Multiplication can run the other way, since two values under one give a smaller result, so 0.40 x 0.40 comes out to just 0.16. A handy move is padding the shorter number with zeros, writing 0.5 as 0.500 so every column has a partner without changing its size at all. A few of the sets also build in the small checks that catch mistakes, like noticing when a sum lands exactly on a whole number or when dividing by a tiny value sends the answer soaring. Those quick sanity checks are what stop a misplaced point from turning an answer ten times too big or too small, which is the single most common decimal slip there is. Decimal math turns up every time you handle money or measurement, so the practice pays off well past the screen. Start at the operation that trips you up most and work through the free interactive math quizzes from there.
6 topicsDivisibility
A few quick patterns can tell you whether a big number divides evenly long before you reach for long division. Divisibility rules are those shortcuts, and these quizzes turn them into instant mental checks. Divisibility Rules and Quick Checks You will choose the numbers that divide cleanly and settle true-or-false claims, with prompts asking which value is divisible by 4 or by 9. The first quiz sticks to the friendlier divisors, while the second pushes into tougher ones like 8, 11, 13, and 17, using multiple-choice and all-except style questions. The point is to lean on patterns instead of dividing the long way. A number like 124 is divisible by 4 because its last two digits, 24, are. These sets sit at an intermediate level and reward knowing the tests cold, since a rule is both faster and far less error-prone than long division. The Rules That Feel Like Magic The test for 9 is almost a party trick. Add up all the digits, and if that sum divides by 9, so does the original number, and the very same idea works for 3. Eleven has a cleverer check: alternately add and subtract the digits from left to right, and if you land on 0 or a multiple of 11, the whole number passes too. The sets reward knowing the tests cold, since the whole point is to replace slow long division with a quick glance. You will get comfortable spotting which rule applies, whether a number ends in the right digit for 2, 5, or 10, or its digits add up the right way for 3 and 9. Lean on these enough and you stop reaching for long division on numbers of any size, which is genuinely handy whenever you simplify a fraction or hunt for a factor. These shortcuts show up everywhere, from simplifying fractions to spotting factors, which makes them well worth memorizing.

1 topicDivisibility of Whole Numbers
You might assume the rule for a number like 6 is something you simply memorize on its own. In fact, divisibility of whole numbers often works by stacking two simpler tests together, and these quizzes show you how that trick handles even the awkward divisors fast. Testing Whole Numbers for Divisibility You will pick the number that divides evenly or judge true-or-false statements, with prompts like which value is divisible by 6, or whether 588 is divisible by 7. The first quiz covers the everyday divisors, and the second steps up to harder ones, including divisible-by-all-except questions with numbers like 11 and 13. Rather than dividing the long way, you combine quick tests. Checking 588 for 6, for example, just means confirming it passes the tests for both 2 and 3. The sets run from intermediate to advanced, and treating each test as a building block is what makes the harder divisors feel manageable. Stacking Rules to Crack Bigger Divisors The rule for 6 is really two rules in one, since a number works only if it passes the test for 2 and the test for 3. That is why 588 qualifies: it is even and its digits add to a multiple of 3. You can chain rules the same way elsewhere, since a number divisible by both 3 and 4 is automatically divisible by 12, saving you from ever testing 12 directly. The second quiz leans on divisible-by-all-except questions, where you rule out every option but one, which is a sharper test of whether you really know each rule. Working the divisors as a connected set, rather than a pile of separate tricks, is what makes even large numbers stop feeling intimidating, and once the stacking clicks a glance is often all it takes. The same stacking approach is how you start checking whether a number is prime, ruling out small divisors one at a time.

1 topicFractions
It seems natural to assume two fractions each smaller than one could never add up to more than a whole. Fractions are full of small surprises like that, and these quizzes build the skill from simple halves all the way to thirds, eighths, and beyond. Adding, Simplifying, and Converting Fractions The sets cover the core moves. You will add fractions with unlike denominators like 2/3 + 1/4, reduce busy-looking ones such as 6/18 down to 1/3, take a fraction of a number as in 3/5 of 50, and rewrite fractions as decimals, turning 3/4 into 0.75. The work runs from beginner to intermediate, and finding the common denominator or the biggest shared factor is usually the real job, with the arithmetic falling into place after. You will also meet improper fractions like 5/4, which sit just past a whole. Visual Fractions with a Picture Quiz One set turns fractions into something you can see, showing a group of colorful butterflies and asking what part of the whole one color makes up. Because the answer is right there to count, the idea of a numerator and a denominator clicks in a way bare numbers sometimes do not. The Surprises Inside Simple Fractions Some fractions hide a tidy value, since 7/14 reduces all the way down to 1/2. Others stretch out further than they look, because a neat-seeming 1/8 becomes the three-place decimal 0.125. The sets are arranged so the numbers come out clean, landing on whole values or tidy decimals, which lets you focus on the method instead of messy remainders. Finding the unit fraction first is a shortcut worth building early, since once you know 1/8 of 88 is 11, getting 5/8 of 88 is just multiplying by five to reach 55. These same skills sit underneath percentages, discounts, and tips, so getting quick at them pays off well past the math page. Whether you want to add, reduce, or picture a fraction, start at your level and work through the free interactive math quizzes.
7 topicsGeometry
A handful of formulas and a few clear definitions unlock most of what beginning geometry asks for. These geometry quizzes build that foundation, working through circles, angles, perimeter, and the shapes you name by their sides. Circles, Angles, Perimeter, and Polygons One quiz works through the parts of a circle and how they relate, from the radius and diameter to the area formula A = πr². Another sorts angles by their measure, naming the right angle at 90 degrees and the straight angle at 180. A third builds perimeter from simple squares outward, while a fourth names polygons by their number of sides. The sets run from beginner to intermediate and lean on clear, real examples rather than heavy proofs. You will both recall a formula and use it, which is the surest way to make it stick. The Patterns That Make Geometry Click Most polygon names come straight from Greek number prefixes, so penta means five for a pentagon and hexa means six for a hexagon, which lets a seven-sided heptagon almost name itself. Angles pair up tidily too, since complementary angles add to 90 degrees while supplementary ones add to 180, so the pair with the bigger total is the one that forms a straight line. Those patterns keep paying off. A regular shape's perimeter is just one side length times the number of sides, so a square with 4 cm sides comes to 16 cm and a regular octagon works the same way, while irregular shapes simply have all their sides added together. The circle has its own tidy rule, since multiplying the diameter by pi gives the circumference every time, and recalling a formula and then using it on a real measurement is what makes any of these stick. These basics carry straight into triangles, parallel lines, and everything that follows. Pick the shape you want to start with and work through the free interactive math quizzes.
4 topicsOrder of Operations
You look at 10 - 2 x 4, your eye wants to work left to right, and that is exactly the trap. The order of operations is the set of rules that keeps you from falling for it, and these quizzes drill the right sequence until it feels automatic. Solving Order of Operations Problems Step by Step The beginner sets handle expressions with no parentheses, like 12 / 2 + 6 x 3 and longer chains such as 9 + 3 x 8 / 2 - 5. The advanced sets bring in brackets, where clearing what is inside comes first, in problems like 5 + 3 x (4 + 2) and the multi-step 30 - (6 + 4) / 2 + 15. Each quiz has twelve problems plus a few true-or-false equations to verify, and the steps stay the same no matter how long the expression grows. The difficulty climbs from beginner up to advanced for learners ready for a real challenge. The Catch Most People Miss The name PEMDAS fools a lot of students into reading it as a strict ranking, but multiplication and division share the same priority and are worked from left to right, and the same goes for addition and subtraction. That single misunderstanding is where a surprising number of wrong answers come from. Each problem walks you through the same dependable routine, so by the end the sequence feels natural rather than something you second-guess. The longer chains reward patience, since skipping a single layer is the fastest route to an answer that is just slightly off. This is one of those skills that quietly shows up everywhere, from working out a budget to scaling a recipe up, and once the order clicks with plain expressions, the same logic carries straight over to the tougher problems with parentheses. Get this order right and it carries over to budgets, recipes, and spreadsheet formulas. Open the free interactive math quizzes and see how cleanly you can keep every step in order.
2 topicsRounding Numbers
How do you round a number like 9.5674 to one decimal place without overthinking it? These rounding quizzes give you steady practice trimming both decimals and whole numbers to the place you need. Rounding Decimals and Whole Numbers One group rounds decimals to the nearest tenth, hundredth, and thousandth, with values like 4.5118 becoming 4.51. The other rounds whole numbers to the nearest ten, hundred, and thousand, turning 1,843 into 1,800, with some figures climbing into the tens and hundreds of thousands. Each quiz hands you twelve numbers and takes about five minutes, sitting at the beginner to intermediate level. The rule stays the same no matter how many digits sit in front, so big numbers turn out no harder than small ones. The One Digit That Decides Only the digit right after your target place decides the outcome, and everything further to the right can be ignored once you have spotted it. When that digit is exactly 5, the usual convention is to round up, which keeps your answers predictable. When Rounding Adds a Digit Rounding can change more than one digit at once. A number like 9,774 rounded up to the nearest thousand crosses into five figures, so it actually gains a digit, which surprises people who expect the answer to look about the same length as the number they started with. Practicing across three different place values builds a flexibility that makes any single one feel routine. For whole numbers, each place leans on just one digit to make the call, the ones digit for the nearest ten, the tens digit for the nearest hundred, and the hundreds digit for the nearest thousand. Sometimes rounding up leaves a trailing zero, like a result that ends in .50, and that zero is not optional, since it shows you rounded all the way to the hundredths place rather than stopping early. Want rounding to feel automatic, whether you are estimating a total or reading a scale? Start at your level in the free interactive math quizzes.
2 topicsUnits of Measurement
You're reading a property listing in hectares, or a recipe in pints, and the numbers only make sense once you can convert them. These units of measurement quizzes give you steady practice moving between systems for area, distance, mass, and volume. Converting Area, Distance, Mass, and Volume You will turn 5.0 hectares into acres, 3.0 yards into feet, 4.0 kilograms into pounds, and 1.25 gallons into quarts, working across both the metric and customary systems. Each quiz has ten to eighteen conversions and takes about five minutes, moving from clean whole numbers up to the fiddlier decimal pairings. This is genuinely practical math for cooking, shopping, travel, and reading a map or a land measurement. A bit of repetition turns these from calculator-only tasks into conversions you can estimate in your head. The Conversions That Catch People Out A hectare and an acre sound close in size, but one hectare is about two and a half acres, so a field in hectares is much larger than the same number of acres would suggest. Volume nests in a tidy way by contrast, since a gallon splits into four quarts and each quart into two pints, which means a single gallon hides eight pints inside it. The metric system stays friendly throughout, built entirely on tens, so converting meters to centimeters is just a matter of shifting the decimal point. Once the relationships are second nature, you stop reaching for a calculator and start estimating amounts in your head, which speeds up any task that mixes measurement systems. A couple of catches are worth knowing too, like the weight ounce not being the same as the fluid ounce on a drink bottle, since one measures weight and the other volume. Tons can mislead as well, since a metric tonne is about 2,204.6 pounds rather than the round 2,000 of a US short ton, a gap that matters once you are weighing heavy cargo. Start with the unit you reach for most and get comfortable switching between systems in the free interactive math quizzes.
