Algebra Vocabulary

4. To find the values of any pronumerals that make an equation true.
8. Describes an unknown number if its value can change.
10. To replace each pronumeral in an expression with a number to obtain a final value or evaluate the expression. (e.g. if x = 3 and y = 8 , then x + 2y evaluated gives 3 + 2 × 8 = 19)
13. The values of any pronumerals that make an equation true.
14. A mathematical statement stating that two expressions are equal (e.g. 2 x + 3 = 4y − 2 ).
15. A term that does not contain any pronumerals. It is a number by itself.

1. A number we don't know.
2. A collection of numbers and pronumerals combined with any mathematical operations. (e.g. 2x + 3 ).
3. A letter or symbol used to represent a number we don’t know
5. To find the value of an expression by substituting each pronumeral with a number. (e.g. if x = 3 and y = 8 , then x + 2y evaluated gives 3 + 2 × 8 = 19)
6. To solve an equation by reversing the order of operations and using inverse operations.
7. To solve an equation by performing the same operation to each side.
9. Left-hand-side = right-hand-side. It means an equation is true.
11. Consists of numbers and pronumerals combined with multiplication or division.
12. The number in front of a pronumeral. If there is no number in front, then its value is 1, since 1z and z are equal.
