# VIDEO

Have a look at the demonstration on the video to enhance your learning.

## Example 1:

43 - 22

1. Take the large value 43 and subtract only the tens from the second value 22.
43 - 20 = 23

2. From the value left over 23 subtract the units of the second value, which was 2.
23 - 2 = 21

Total= 21

## Example 2:

265 - 139

1. Subtract the hundereds 200 - 100 = 100
2. Subtract 65 - 30 = 35
3. Subtract 35 - 9 = 26

Total = 126
