Term
 Expression
Definition
 Combination of  constants, variables, and products of both. Expressions have no equal sign and can't be solved. They can be simplified using order of operations and combining like terms.   Ex: 4 + 9a - 2b

 Distributive Property
Definition
 multiplying a number by a group of numbers added together is the same as doing each multiplication separately.EX: 3(2 + 4) = 3×2 + 3×4So the "3" can be "distributed" across the "2+4" into 3 times 2 and 3 times 4.
