Inequalities
Inequalities compare ordered values; multiplying by a negative number reverses the inequality.
Linear equations
A one-variable linear equation has the form ax+ with a nonzero for a unique solution.
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.
Exponent laws
Power identities simplify products and quotients where bases and exponents satisfy the required domain conditions.
