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.
How to get the last two math facts of the family. . . So far we ve recreated 8 + 5 = 13 and 5 + 8 = 13. Since we know the inverse (opposite) of addition is subtraction, start with the sum (or the larger number), 13, and subtract one of the addends. 13 8 = 5 Of course, your answer is the third number. In this case, the answer is 5. Thus the next fact would be, 13 5 = 8.
