2. TERM
Definition: A part of an expression that is separated by an addition or subtraction sign.
Examples:
In the expression 2x – 4 the terms are 2x and – 4.

3. CONSTANT TERM
Definition: A single number.
Examples: 5 -3
8.26

4. COEFFICIENT Definition: Examples:
A coefficient is the factor in front of the variable or variables of a term.
Examples:
In the algebraic expression x – 8xy + 7.3y,
1, -8 and 7.3 are the coefficients of the first, second, and third terms, respectively.
***NOTE: x is the same as 1x

5. VARIABLE
Definition: A symbol, usually a letter, that is used to represent one or more numbers in an algebraic expression.
Example: a, b, x
4a + 3
3b + 2
6x + 2

6. LIKE TERMS
Definition: Contain the same variables raised to the same exponents, or are both constant terms.
Examples:
4b and -5b
6xy2 and 7xy2
12 and 7

7. MONOMIAL
Definition: An algebraic expression consisting of only one term.
Examples: 4x 2 -x
16x2

8. DEGREE OF ONE VARIABLE MONOMIALS
Definition
The degree of one variable monomials corresponds to the exponent on the variable.
Example:
-2x3 the degree is 3

9. DEGREE OF MONOMIALS WITH MANY VARIABLES
Definition
The degree of a monomial with many variables is equal to the sum of the exponents given to the variables making up this monomial.
Example:
-3x2y3 is a monomial with two variables x and y its degree is 5 (2+3)

10. BINOMIAL Definition: A polynomial that has two terms. Examples: 4x +1

11. POLYNOMIAL
Definition: An expression that has one or more terms of the form axn where a is any real number and n is a whole number.
Examples:
4x +1
3x2 + 2x +1
