Vocabulary Words

2. an algebraic expression consisting of one term.
3. In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members
5. A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x , y , and z are common generic symbols used for variables
7. a number or quantity that when multiplied with another produces a given number or expression.
8. The form of an algebraic expression in which no part of the expression can be made simpler by pulling out a common factor
9. In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs
10. A fixed value. In Algebra, a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. Example: in "x + 5 = 9", 5 and 9 are constants. If it is not a constant it is called a variable.

1. A fraction is in simplest form when the top and bottom cannot be any smaller (while still being whole numbers). Example: 2/4 can be simplified to 1/2. To simplify a fraction, divide the top and bottom by the highest number that can divide into both numbers exactly
4. A number or symbol multiplied with a variable or an unknown quantity in an algebraic term. For example, 4 is the coefficient in the term 4x, and x is the coefficient in x(a + b). A numerical measure of a physical or chemical property that is constant for a system under specified conditions.
6. Since all they did was regroup things, this is true by the Associative Property. Commutative Property. The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around.
