About Scientific Calculator
Supported functions
sin, cos, tan, asin, acos, atan, log (base 10), ln (natural log), sqrt, abs, exp. Constants: pi, e. Operators: + - * / ^. Trig functions use radians.
Why log is base 10
Convention: "log" alone = base 10 (common log), "ln" = natural log (base e). Programmers reverse this — Math.log in most languages is natural log. This calculator follows the math convention.
Order of operations
Standard PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction. Use parens generously to avoid ambiguity.
