Inverse functions
An inverse reverses a bijection; domain restrictions can make a function invertible.
Logarithms
A logarithm is the inverse of an exponential, defined for positive arguments over the reals.
Absolute value
Absolute value measures distance from zero on the real line.
Algebraic expressions
Expressions combine constants, variables and operations without necessarily asserting an equation.
Arithmetic operations
Addition, subtraction, multiplication and division follow precedence rules; division by zero is undefined.
