85736 - 69458
Place one number above the other, so that the ones', tens', hundreds', thousands' places, and so on, are lined up. Draw a line under the bottom number.
85736
- 69458
Subtract 8 from 6. The digit being subtracted is larger than the digit above it, regroup digits by borrowing a digit from the next column on the left, subtract (16 - 8 = 8) and place the answer below the line in the column being subtracted.
