Simple Math – Quick Cheat Sheet

• Operators: ^ (power), * (multiply), / (divide), % (mod), + (add), - (subtract).
• Order of operations: Parentheses → ^ → * / % → + -. Power is right-associative: 2^3^2 = 2^(3^2) = 512.
• Unary minus: You can write -5 + 3 or (-3+8)*2.
• Decimals: Use a dot: 3.14 * 2.
• Modulo: a % b returns the remainder (uses floating-point fmod).
• Errors: Division/modulo by zero, mismatched parentheses, or unsupported characters will show a clear message.
