About
Calculator evaluates full math expressions — not just one operation at a time — with parentheses, exponents, and common functions, keeps a session history of your last 50 calculations, and has quick-insert buttons for constants like π, e, and √2. It's a real expression evaluator, so typing (3+4)*2^10 works directly instead of requiring buttons pressed in sequence. Runs entirely in your browser.
