A little guidance.
Evaluate real-valued expressions with +, −, *, /, ^, parentheses, pi, e, and postfix factorial (!). Supported functions: sin, cos, tan, sqrt, abs, ln, log, exp, floor, ceil. Function arguments require parentheses and multiplication must be explicit. Expressions are parsed locally without eval.

Good to know.
How are powers and negative numbers interpreted?
Powers associate right to left: 2^3^2 = 512. Unary minus follows power precedence: -2^2 = -4. Factorial accepts whole numbers from 0 through 170. Complex results are not supported.
