Exponentiation

Exponentiation is a mathematical operation involving two numbers, the base (b) and the exponent (n) (or index or power).

<math>base^{exponent} = power</math>

<math>b^n = power</math>

Exponentiation (**).

Logarithm

Mathematics - Logarithm Function (log)

<math> log_{base}(power) = exponent </math>

Increment/ decrement

  • ++: increment
  • decrement
