Curriculum topic:   Number: Addition and Subtraction

Curriculum subtopic:   Solve Add/Subtract Problems to 20

Difficulty level:   ### QUESTION 1 of 10

We can add and subtract to find missing numbers. Look at this problem. + 2 = 5

We can find the missing number like this.

 5 - 2 = 3

Subtract 2.

5 - 2 = 3.

The missing number is 3.

Now check.

 3 + 2 = 5

Find the missing number. ? + 2 = 8

Find the missing number. ? + 5 = 9

Find the missing number. ? + 3 = 8

Find the missing number. ? + 1 = 6

Find the missing number. ? + 4 = 7

Find the missing number. ? - 7 = 3

Find the missing number. ? - 1 = 2

Find the missing number. ? - 5 = 1

Find the missing number. ? + 5 = 9

Find the missing number. ? + 2 = 5
