Solve Vertical Subtraction: 72 minus 8 Step-by-Step

Let us solve the subtraction problem $72 - 8$ step-by-step.

1. Write the numbers vertically, ensuring that the digits are aligned by place value:

• 72
  - 8
  $\underline{\phantom{776}}$

2. Subtract the digits in the units column:

• Since $2$ is smaller than $8$, we need to borrow from the tens column.
• Adjust the tens digit from $7$ to $6$ (because we borrow 10 from it) and make the units digit $2 + 10 = 12$.

3. Now perform the subtraction for the units column:

• Subtract $8$ from $12$, which equals $4$.

4. Now, focus on the tens column:

• Subtract the adjusted tens digit, $6$, from $0$ (as there is no digit under it in the subtrahend), resulting in $6$.

5. This gives us the final answer:

• The result of $72 - 8$ is $\mathbf{64}$.

Therefore, the solution to the problem is $64$.
