Advanced scientific & engineering calculator
Tip: type directly with your keyboard — Enter evaluates, Esc clears.
Three calculators in one. A quick tour:
Type with your keyboard or tap the keys. Enter evaluates, Esc clears. Switch DEG / RAD / GRAD, use 2nd for inverse functions, and revisit any result from History.
Choose an operation — solve, derivative, integral, simplify, expand, factor — then enter an expression such as x^2 - 5x + 6 = 0 and the variable. Tap an example to try it instantly.
Factorials, permutations, combinations, binomial and normal distributions, plus unit conversion across ten categories. Everything recalculates as you type.
