How to Use

Basic Arithmetic

Use +, −, ×, ÷ for basic operations. Use % for percentages — e.g. 150×20% gives 30.

Trigonometry

sin(30), cos(45), tan(60) — switch between Degrees and Radians using the DEG/RAD toggle.

Logarithms

log(100) = 2 (base 10), ln(e) = 1 (natural log). Critical for finance, science, and engineering.

Square Root

√(25) = 5. For cube roots: use x^(1/3). For nth root: use x^(1/n).

Exponents

x² squares the current value. x^y lets you enter any base^exponent, e.g. 2^10 = 1024.

Constants

π = 3.14159265… (pi). e = 2.71828182… (Euler's number). Both can be used in expressions.
