How it works: Calculator

Type a formula such as (1250 × 3 + 500) ÷ 4 or use the keypad; the result appears as you type. Press Enter or = to keep it in the history. Use ^ for powers, sqrt( ) for square roots, % to divide by 100, ! for factorials and π.

Trigonometry works in degrees by default and can switch to radians. The usual order of operations applies (multiplication before addition), unlike some pocket calculators that work step by step.

FAQ

Can I use the keyboard?

Yes — * to multiply, / to divide and Enter to calculate.

Why is 2+3×4 = 14?
