Math

Most everyday math is simple — but only when the numbers stay small and the clock is not ticking. The math calculators here handle the calculations people meet most often: finding a percentage of an amount, working out what percentage one number is of another, measuring percentage change between two values, adding and simplifying fractions, and averaging a list of numbers with the mean and median computed together. Each tool explains the formula it uses and walks through a realistic example, so you can verify the logic rather than trusting a black box. Students use them to check homework; shoppers use them to compare discounts; analysts use them to sanity-check figures before they go into a report. Enter values in any format you like — the parser even accepts Arabic-Indic digits — and the result appears instantly, rounded sensibly and shown with the full unrounded value where it matters.
