Functions
A function assigns exactly one output to each input in its domain; its domain matters when comparing expressions.
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.
