How to Use the Random Math Problem Generator
Pick a difficulty (easy, medium, hard) and a type (arithmetic, fractions, probability), then click "Generate Problem" to get a new math problem on the spot. Click "Show Answer" whenever you want to check it, and click "Generate Problem" again for a fresh one whenever you're ready for another round.
Arithmetic problems scale their number range with difficulty, and division problems are always built to divide evenly so they stay clean to practice. Fractions randomly generate addition or subtraction between two fractions with different denominators, with the answer automatically simplified. Probability problems ask for the chance of drawing a red ball from a bag of red and blue balls, with the answer shown as both a simplified fraction and a percentage.
Every problem is generated and solved live in your browser, so the displayed answer is always correct for that exact problem. It's a handy way to build a daily habit of a few practice problems, whether for a kid working on arithmetic or for your own quick mental math workout.
