Column traversal from right to left
Thousandths column:
Thousandths column:
- Since 0 is less than 2, we have to borrow 1 from the Hundredths column
- As a result, 0 becomes 10, and 10 − 2 = 8
- The 5 in the Hundredths column becomes 4
Hundredths column:
- Since 4 is less than 9, we have to borrow 1 from the Tenths column
- As a result, 4 becomes 14, and 14 − 9 = 5
- The 8 in the Tenths column becomes 7
Tenths column:
- 7 − 6 = 1
Ones column:
- 0 − 0 = 0
