| A | B |
| algebraic expression | A mathematical phrase that has at least one variable and one operation. |
| variable | A quantity that can change or vary, often represented with a letter. |
| Commutative Property of Multiplication | 3x5=5x3 The order in which numbers are multiplied does not change the prodect of the numbers. |
| Commutative Property of Additiion | 5+2=2+5 The order in which numbers are added does not change the sum of the numbers. |
| Associative Property of Addition | 1+(3+4)=(1+3)+4 The way numbers are grouped does not affect the sum. |
| Indentity Property of Addition | 6+0=6 Adding zero to a number does not change the number. |
| order of operations | A set of rules mathematicians use to determine the order in which operations are performed. (PEMDAS or PEDMSA) |
| evaluate | To find the value of an expression. |
| Associative Property of Multiplication | 6x(4x5)= (6x4)x5 The way numbers are grouped does not affect the product. |
| Indentity Property of Multiplication | 4x1=4 The product of a number and one is that number. |
| Distributive Property | 5(3+4)=(5x3)+(5x4) Multiplying a sum (or difference) by a number gives the same result as multiplying each number in the sum (or difference) by the number and adding (or subtracting) the products. |
| substitution | To replace a variable with a number. |
| imput/output table | A table of related values. |
