Foundations of Algebra

8. The part of the term that tells how many times the number is used as a factor such as 3 in 2^3
9. To simplify 3-(-5) we can -- -- -- to get 3+5 (3 words)
10. The first part of a term, it's numerical factor such as 2 in 2x+8
12. The value(s)that can be substituted for variable(s)to make an equation true
14. Any number that can be written with integers in the form of a/b where b is not 0 (2 words)
17. The process of calculating the value of an expression to its best final answer, sometimes involving substituting in the value of a variable
18. The square root of 14 in not an integer
19. A mathematical sentence with an equal sign. It has a LHS and RHS
20. The part of the term that is the factor being repeated such as 2 in 2^3

1. A mathematical statement such as (12-3)4-7 or 2x+8
2. The property illustrated by a+b=b+a
3. A term that has no variable such as 8 in 2x+8
4. PEMDAS (3 words)
5. ...-2, -1, 0, 1, 2,...
6. The property illustrated by 2(x-3)= 2x-6
7. Any number that lies on the number line (2 words)
11. To -- an algebraic expression, you substitute a given number for each variable then simplify
13. Numbers like pi, the sq root of 7, 2.3257892357...
15. 2ab+5ab-ab but not 2a+5b-ab (2 words)
16. Subtraction and Division are Commutative operations
