Solve Vertical Subtraction: 48 minus 7

To solve this problem, we'll follow these steps:

• Step 1: Align the numbers vertically by place value.

• Step 2: Subtract the units place.

• Step 3: Subtract the tens place if necessary.

Now, let's work through each step:
Step 1: Write the numbers 48 and 7 in columns where the digits (ones place) are aligned: $\begin{array}{c} 48 \\ -~7 \\ \end{array}$ Step 2: Subtract the units (8 - 7 = 1) and write the result in the units position.
Step 3: The tens place after subtraction is unchanged because there is no borrowing needed, so the 4 from 48 stays as 4.
Thus, we have: $\begin{array}{c} 48 \\ -~7 ~~\\ \underline{41} \end{array}$

Therefore, the solution to the problem is 41.
