The Math Calculator is now a scientific calculator that evaluates a typed expression instead of button-by-button taps.
- Calculate with a single expression: type functions and real parentheses directly, like sin(30), log(100), or (2+3)*4.
- Trig, logs, and factorials: pick engineering functions like asin/acos/atan, log₂/logₙ, n!, nPr/nCr, gcd/lcm from the Functions keypad.
- DEG/RAD switch: change the angle unit with one button, and every trig calculation follows it.
- Parenthesis error alerts: if a parenthesis is left open, it tells you exactly how many are unclosed before calculating.
- Copy and shortcuts: copy the result with a button or Ctrl+C, and use Enter/Esc to calculate or clear instantly.
- Every calculation happens entirely in this browser and is never sent to a server.
