Variable
A letter or symbol that stands for an unknown number
Constant
A number that never changes (the numbers that are not attached to the variable)
Algebraic Expression
Contains variables, operations and numbers and does not have an equal sign (directions will usually ask you to simplify)
Distributive Property
Multiplying a factor across multiple terms.
Terms
Part(s) of an algebraic expression of equation that are separated by + or - (always include the sign in front of the term)
Like Terms
The terms that have the same variables (constants are also like terms)
Simplify
To put an expression in its simplest form by combining like terms. The expression does not have parentheses or like terms.
