### QUESTION 1 of 10

This worksheet is about finding missing digits.

Missing digits are shown with a .

Example

Choose the two digits between 0 and 9 which make this subtraction correct.

8♦  -  ♦4  = 23

Look at

8  -  4  = 23

To get an answer of 23, we can tell that:

The missing units digit must be 4 + 3 = 7

So now we have

87  -  4  = 23

The missing tens digit must be 8 - 2 = 6

This gives the statement 87  -  64  = 23
