Subtracting Whole Numbers By lining them up…

Find the result of subtracting 48 from 152 Find the result of subtracting 48 from 152. First, line them up aligned right: 152 - 48

Find the result of subtracting 48 from 152. As one has been borrowed, the 5 is crossed out and replaced by a 4 4 1 Since 8 cannot be taken from 2, a one from the tens column is borrowed and written next to the 2 to make 12. 12-8=4 so write a 4 below the first column. 152 - 48 4

Find the result of subtracting 48 from 152. 4 1 152 - 48 04 4-4=0 so a zero is written below the middle column

Find the result of subtracting 48 from 152. 4 1 152 - 48 104 1-0=1 so a one is written below the first column
