What is 73 - 64

Answer: 73 - 64 = 9

Subtraction using Regrouping or Borrowing

  • Step 1: Arrange the numbers 73, 64 to align them properly in respective columns for ones, tens, hundreds, and Thousands… stacking them vertically.
  • Step 2: Begin by subtracting the digits in the one's place. If the bottom digit is greater than the top digit, borrow 1 from the tens column which will be combined to the number at the one's place.
  • Step 3: After giving 1 to the one's place, the number at the ten's place will be reduced by one number. Next, subtract the numbers at the one's place.
  • Step 4: We apply step 2 to the remaining digits in two-digit and larger numbers. As and when we borrow, we subtract the numbers simultaneously. Finally, we get the answer as 9
