How to write expressions

Standard math syntax works: (3 + 4)^2 / sqrt(2), sin(pi/6), log(1000). Functions use parentheses; ^ is exponentiation; ln is natural log while log is base-10. Switch to degrees when working with everyday angles — sin(30) in degree mode returns 0.5.

Order of operations

Evaluation follows PEMDAS with right-associative exponents, so 2^3^2 is 2^(3^2) = 512, and unary minus binds tightly: -3^2 reads as (−3)² = 9 here. When in doubt, add parentheses — they cost nothing and remove every ambiguity.
