Let's solve the subtraction problem :
Align the numbers vertically to ensure each digit is in the correct place value position:
Write 105 as:
Place 3 beneath 105 such that it aligns with the rightmost digit (units place):
Subtract each column starting from the rightmost side (units digit) to the left:
Step-by-step subtraction:
Units column:
Tens column: There is nothing to subtract with 0, so it remains .
Hundreds column: Similarly, there is nothing to subtract, so it remains .
Combine the results of these steps to find the answer:
The result of the subtraction .
Therefore, the correct answer is .
102
\( \begin{aligned} &97 \\ -& \\ &63 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)\( \)
Vertical alignment ensures each digit is in its correct place value position. When you align properly, you subtract units from units, tens from tens, and hundreds from hundreds!
When there's no digit to subtract (like in the tens and hundreds columns here), the original digit stays the same. Think of it as subtracting zero from that digit.
Yes! Always start subtracting from the rightmost column (units place) and work your way left. This follows the proper place value order and prevents errors.
Add your answer to the number you subtracted. If you get the original number, you're correct! For example: ✓
In this problem, you don't need to borrow since . But when the top digit is smaller than the bottom digit, you borrow from the next column to the left.
