Multiplication sign * is not necessary and can be omitted. Examples: 0.5x^3-3x or pixeln (2cos [LN2x]) or Pipi/ (Exe) Using different types of grouping symbols (parentheses, brackets, braces) for clarity of nested expressions is optional, but not necessary. Exponentiation base exponent, for example p (x,2) or x^2 .
