Subtract 8 from 72: Vertical Format Arithmetic Problem

To solve this vertical subtraction problem, follow these steps:

Step 1: Set up the problem vertically.

Write 72 and 8 ensuring that the digits are aligned according to their place values:

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

Step 2: Start subtracting from the rightmost digit (ones place).

In the ones place, we have 2 (from 72) and 8 (from -8). Since 2 is less than 8, we need to regroup.

Step 3: Perform regrouping.

Take 1 ten from the tens place of 72, leaving 6 tens. Adding 10 ones to 2 makes it 12 in the ones place.

Rewritten, the problem now looks like this:

6 12
- 8
$\underline{\phantom{72}}$

Step 4: Continue with subtraction in the ones place.

Subtract 8 from 12, which equals 4.

Step 5: Subtract in the tens place.

Now, move to the tens place. We have 6 tens (from the regrouped value) and since there is no tens digit to subtract, it remains 6.

Conclusion: Combine the results from each place value to find the final difference: $6$ tens and $4$ ones make $64$.

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