Term | Definition |
Exponent | Indicates the number of times the base is to be used as a factor. |
Evaluate | means to find its value. |
Order of operation | the rule that lets you know which operation to perform first |
Evaluate Algebraic Expressions | replace the variable with their values. Then find the value of the numerical expression using the order of operation. |
algebraic expression | sums and/or products of numbers and variables |
variable | symbols used to represent unknown numbers or values |
term | number, variable, or a product or quotient of numbers and variables |
factor | in multiplication, the quantities being multiplied |
product | the result of multiplying two or more quantities |
Equivalent expressions | expressions that represent the same number. |
Additive Identity | For any number a, the sum and a and 0 is a. |
Multiplicative Identity | For a number a, the product of a and 1 is a. |
Multiplicative Property of Zero | For any number a, the product of a and 0 is 0 |
Multiplicative Inverse (reciprocals | For every number a/b, where a, b ≠ 0, there is exactly one number b/a such that the product of a/b and b/a is 1. |
Commutative Property | The order in which you add or multiply numbers does not change their sum or product. |
Associative Property | The way you group 3 or more number when adding or multiplying does not change their sum or product. |
Distributive Property | When you multiply a number by a group of numbers added together you get the same answer as when you do each multiplication separately |
Like Terms | terms that contain the same variables, with corresponding variables having the same power. |
Simplest Form | when an expression contains no like terms and parentheses. |
Coefficient | The numerical factor of a term. |
