2. Algebra
the branch of mathematics that deals with relationships between numbers, utilizing letters and other symbols to represent specific sets of numbers, or to describe a pattern of relationships between numbers

3. Coefficient
a number multiplied by a variable in an algebraic expression

4. Expression
a mathematical phrase involving at least one variable and sometimes numbers and operation symbols.

5. Factor
for any number x, the numbers that can be evenly divided into x are called factors of x; the number 20 has the factors {1, 2, 4, 5, 10, & 20}

6. Term
a value in a sequence--the first value in a sequence is the 1st term, the second value in a sequence is the 2nd term, and so on; a term is also any of the monomials that make up a polynomial

7. Variable
a letter of symbol used to represent a number

8. Y-intercept
the point where a line meets or crosses the y axis

9. Binomial Expression
An algebraic expression with two unlike terms. Ex. 3x + 2

10. Capacity
The greatest volume that a container can hold.

11. Circumference
The distance around a circle.

12. Constant Term
A quantity that does not change it value

13. Integer
The set of numbers Ex ,-2,-1,0,1,2,3.....

14. Irrational Number
A number whose decimal form is nonterminating and nonrepeating. They cannot be written in the form a/b, where a and b are integers (b cannot be zero). So all numbers that are not rational are irrational.

15. Monomial Expression
Algebraic expression with one term. Ex. 3x

16. Pythagorean Theorem
It is a theorem that states a relationship that exists in any right triangle. If the lengths of the legs in the right triangle are a and b and the length of the hypotenuse is c, we can write the theorem as the following equation a^2 + b^2 = c^2. Radical the symbol, square root of (b&a), which is read "the bth root of a," is called a radical.

17. radical
The square root symbol

18. Radicand
The number underneath the root symbol. So, in square root of b = a, the b is called the radicand

19. Rational Number
A number expressible in the form a/b or -a/b for some fraction a/b. The rational numbers include the integers.

20. Standard from of Polynomial
To express a polynomial by putting the terms in descending exponent order.

21. Trinomial
An algebraic expression with three unlike terms.

22. Volume
The amount of space occupied by an object.

23. Whole Numbers
The numbers 0,1,2,3.....
