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.
Adding and subtracting mixed numbers. In this section, we will write addition and subtraction statements for mixed numbers using given diagrams. First, we will add and subtract the whole numbers. Second, we will add and subtract the fractions. Some of the fractions will have like denominators and others will have unlike denominators.
