Key Concepts

  • Addends and sums.
  • Use the addition fact patterns to find the sum.

Introduction

Addends

Addends are any of the numbers that are added together. For example: In the addition equation 8 + 3 = 11, the 8 and the 3 are addends. 

Addition: 

Example 1: 

Find the addends and sum for the equation given below. 

3 + 4 = 7 

parallel

Solution: 

3 and 4 are addends. 

7 is the sum.
