| POWER | A PRODUCT THAT IS MADE BY A SINGLE FACTOR BEING MULTIPLIED BY ITSELF. |
| BASE | THE FACTOR THAT IS MULTIPLIED BY ITSELF IN A POWER. |
| EXPONENT | THE NUMBER THAT TELLS YOU HOW MANY TIMES A FACTOR IS MULTIPLIED BY ITSELF. |
| EXPRESSION | A NUMBER, A LETTER OR THE COMBINATION OF NUMBERS AND/OR LETTERS SEPARATED BY OPERATIONAL SIGNS. |
| EVALUATE | TO FIND THE VALUE OF AN EXPRESSION BY SUBSTITUTING THE VARIABLES WITH THEIR VALUES AND THEN CALCULATING |
| SUBSTITUTION | REPLACING A VARIABLE WITH A VALUE. |
| EQUATION | A MATHEMATICAL SENTENCE THAT USES AN EQUAL SIGN TO STATE THAT TWO EXPRESSIONS HAVE THE SAME VALUE EXAMPLE: 2X + 4 = 7 |
| SIMPLIFYING | THE ACT OF GETTING AN EXPRESSION INTO IT'S SIMPLEST FORM. |
| FORMULA | AN EQUATION THAT SHOWS THE RELATIONSHIP BETWEEN TWO OR MORE VARIABLES. EXAMPLE: P = 2L + 2W |
| EXPONENTIAL NOTATION | A METHOD OF WRITING THE MULTIPLICATION OF FACTORS BY USING EXPONENTS |
| FACTORS | NUMBERS, LETTERS OR THE COMBINATION OF NUMBERS AND LETTERS THAT WHEN MULTIPLIED TOGETHER FORM A PRODUCT |
| REPLACEMENT SET | THE SET OF NUMBERS FROM WHICH YOU CAN SELECT REPLACEMENTS FOR THE VARIABLE IN AN OPEN EQUATION. |
| SOLUTION | A REPLACEMENT FOR A VARIABLE THAT MAKES AN OPEN SENTENCE INTO A TRUE EQUATION |
| SOLUTION SET | THE SET OR COLLECTION OF ALL OF THE SOLUTIONS OF AN EQUATION. |
| COLLECTING LIKE TERMS | TO SIMPLIFY AN EXPRESSION BY PUTTING TOGETHER TERMS THAT HAVE EXACTLY THE SAME VARIABLE FACTORS. |
| EQUIVALENT EXPRESSIONS | TWO MATHEMATICAL STATEMENTS THAT HAVE THE SAME VALUE BUT MAY LOOK DIFFERENT. EXAMPLE: 2X + 4 + 3X + 7 = 5X + 11 |
| DISTRIBUTIVE PROPERTY | THE PROPERTY THAT IS MODELED BY A(B + C) = AB + AC EXAMPLE: 7(2X + 5) = 14X + 35 |
| MULTIPLICATIVE IDENTITY PROPERTY | A x 1 = A |
| COMMUTATIVE PROPERTY | THE PROPERTY THAT SAYS THAT WHEN YOU ADD OR MULTIPLY, ORDER DOESN'T MATTER. 2+3 = 3+2 ; (3)(4) = (4)(3) |
| ASSOCIATIVE PROPERTY | THE PROPERTY THAT SAYS THAT WHEN YOU ADD OR MULTIPLY, THE GROUPING DOESN'T MATTER. EXAMPLE: 2+(3+4) = (2+3)+4 |
