Addition (often signified by the plus symbol +) is one of the four elementary, mathematical operations of arithmetic, with the others being subtraction, multiplication and division. The addition of two whole numbers is the total amount of those quantities combined. For example, in the picture on the right, there is a combination of three apples and two apples together; making a total of 5 apples.
Addition and Subtraction of Algebraic Expressions. 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.
