Fracsy is a fraction calculator that shows its work. Add, subtract, multiply and divide fractions, get an exact answer instantly, then tap once to see every step.

Type fractions the way you write them: stacked, with a real numerator and a real denominator. No decimals unless you want them. No rounding errors. 1/3 + 1/4 gives you 7/12, not 0.5833333.
