Before we see how to add and subtract integers, we define terms and factors.
Terms and Factors
A term in an algebraic expression is an expression involving letters and/or numbers (called factors), multiplied together.
Example 1
The algebraic expression
5x
is an example of one single term. It has factors 5 and x.
The 5 is called the coefficient of the term and the x is a variable.
Example 2
5x + 3y has two terms.
First term: 5x, has factors and x
Second term: 3y, has factors and y
The and are called the coefficients of the terms.
Example 3
The expression
has three terms.
First term: has factors and x2
Second term: has factors , a and b
Third Term: ; has factors , , and .
The , and are called coefficients of the terms.
