🔢 Math

Percentages, fractions, averages, geometry, algebra, statistics — the math tools here cover the calculations that come up in school, work and everyday life. Enter your numbers, see the worked result instantly, and copy it wherever you need.

Each calculator shows the formula behind the result, so you can verify the steps instead of trusting a black box. That makes them handy for homework checks, quick estimates at work and double-entry bookkeeping of your own reasoning.

Tools range from everyday arithmetic (percent change, tips, discounts) through geometry (areas, volumes, angles) to statistics (averages, spread, probability) and unit-based math.
