# SUBTRACTION

##### Hello children, welcome back to class

In our last lessons we learnt about subtracting 1 digit and 2-digits numbers. In this lesson, we will be learning subtraction involving additions; where we will be required to find missing addends.

In math, an add end can be defined as the numbers added together to form the sum.

To find the missing addend we observe that one addend is given along with their sum so, to find the other addend (missing) of the problem we need to calculate both the numbers showing in the question to get the exact answer.

For example: 1 + ? = 6

To find the missing addend we read the question given as ‘1 and how many more make 6?’ The answer is 5. Therefore, when the number is put in the place of the question mark (?), the sum is written as 1 + 5 = 6.

So, the missing addend is 5.

ACTIVITY

1. (i) 6 + ? = 9

1. (i) ? + 5 = 5

1. (i) 4 + ? = 7

1. (i) ? + 6 = 8

1. (i) 1 + ? = 4

1. (i) 8 + ? = 9

1. (i) ? + 2 = 5

1. (i) ? + 3 = 6

1. (i) 0 + ? = 1

1. (i) ? + 2 = 7

1. (i) ? + 1 = 3

1. (i) ? + 9 = 9
