Subtraction with borrow
Sometimes when you subtract you need to regroup 1 ten as 10 ones.
 Question Step 1 Step 2 Step 3

• Start from the ones place
• In the ones place, since we cannot subtract 9 from 5, we borrow 1 from 3 and make it 2.
• In ones place we get 15-9 = 6
• In the tens place, since we have taken out 1 from 3, we have 3-1=2
• Since we cannot subtract 8 from 2, we borrow 1 from 5 and make it 4.
• In hundreds place, we have 5-3=1
