Algebraic Relationship Vocabulary
Term | Definition |
---|---|
Associative Property | No Matter how numbers are grouped, the answer will always be the same |
Associative Example | (4 + 2) + 6 is the same as 4 + (2 + 6) |
Associative Example | (2 x 3) x 4 is the same as 2 x (3 x 4) |
Base Number | A number to be raised to a power |
Base Number Example | 10 to the 1 Power = 10 |
Base Number Example | 10 to the 2 Power = 10 x 10 |
Commutative Property | In addition and multiplication, Numbers may be added or multiplied together in any order |
Commutative Example | A + B = B + A |
Commutative Example | A x B = B x A |
Distributive Property | Multiplying a number is the same as multiplying its addends by the number then adding the products |
Distributive Example | 6 x 9 is the same as 6 x (4 x 5) is the same as (6 x 4) + (6 x 5) = 24 + 30 = 54 |
Equation | A mathematical statement containing an equals sign, to show that two expressions are equal |
Equation Example | 2 + 2 = 4 |
Equation Example | 5x + 10 = 35 |
Exponent | Is a small number placed to the upper right of a base number which shows how many copies of a base number are multiplied together |
Exponent Example | 5 to the 4 power = 5 x 5 x 5 x 5 = 625 |
Expression | Is one or a group of terms and may include variables, constants, operations and grouping symbols. |
Expression Example | 3(X + Y) - 8 + 2x |
Identity Property | When zero is added to a number the result is the number itself. When one is multiplied to a number the result is the number itself. |
Identity Property Example | 12 + 0 = 12 , X + 0 = X , 6x + 0 = 6x |
Identity Property Example | 12 x 1 = 12 , X x 1 = X , 6X x 1 = 6X |
Inverse Operations | Opposite, Reverse operations - Addition and Subtraction Multiplication and Division |
Inverse Operations Example | 4 + 2 = 6 --------> 6 - 4 = 2 |
Inverse Operations Example | 2 + 4 = 6 ---------> 6 - 2 = 4 |
Variable | A quantity that can change or vary, taking on different values. It may be represented by any letter of the alphabet. |
Dependent Variable | The " Output " value of a function as in Y = X squared ---- Y is the Dependent variable |
Independent Variable | The " Input " Value of a function as in Y = X squared ----- X is the dependent variable |
