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: 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:
Therefore, the solution to the problem is 41.
41
\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
Proper alignment ensures you subtract like place values - ones from ones, tens from tens. When digits aren't aligned correctly, you end up subtracting different place values, which gives wrong answers.
In this problem, 8 is larger than 7, so no borrowing is needed. When the bottom digit is larger, you would need to borrow from the next column to the left.
Yes! Always start with the ones place (rightmost column) and work your way left. This ensures proper borrowing if needed and maintains place value order.
Use addition to check subtraction! Add your answer (41) to the number you subtracted (7). If you get the original number (48), your subtraction is correct: 41 + 7 = 48 ✓
