Like termsTwo or more terms in an expression that have the same variables raised to the same powers.
EquationA statement that two expressions are equivalent.
IdentitiesEquations that are true for all values of the variable.
Conditional equationsEquations that are not true for all values of the variables they contain.
Equivalent equationsEquations that have the same solutions.
Commutative Property of AdditionChanging the order of the addends does not change the sum.
Commutative Property of MultiplicationChanging the order of the factors does not change the product.
Associative Property of AdditionChanging the grouping of the addends does not change the sum.
Associative Property of MultiplicationChanging the grouping of the factors does not change the product.
Inequalitiesmathematical sentences that contain an inequality symbol.
