Variable is a symbol used to represent one or more unknown numbers. It is common to use letters of the alphabet for variables. ex: x, y, z, m
Algebraic Expression is a combination of individual terms and variables separated by plus or minus signs. An expression does not have an “equals” sign.
Like Terms are terms whose variables (such as x or y) AND their exponents (such as the 2 in x2) are the same.
Equivalent expressions are two expressions that are equivalent if they have the same value. Example: 2 + 3 is equivalent to 1 + 4.
