|---|---|
| Algebraic expressions | They have at least one variable and one operation. |
| Variable | A letter that represents an unknown value. |
| Constant | A term without a variable. |
| Coefficient | The number part of a term with variables. |
| Term | A single number or variable, or numbers and variables multiplied together. Terms are usually separated by addition and subtraction signs. |
| Like terms | Two or more terms with the same variable or exponent. |
| Algebraic expressions | Have at least one variable and one operation |
| Sum | The answer of an addition problem |
