To solve this subtraction problem, we will use the vertical subtraction method as follows:
Step 1: Align the numbers vertically.
We write 248 over 135, ensuring that corresponding digits are aligned correctly, particularly the units, tens, and hundreds places.
\begin{array}{c} 248 \\ - 135 \\ \hline \end{array}
Step 2: Subtract column by column from right to left.
Units column: . Write 3 under the units column.
Tens column: . Write 1 under the tens column.
Hundreds column: . Write 1 under the hundreds column.
The subtraction does not require any borrowing as each digit in the minuend is greater than or equal to the corresponding digit in the subtrahend.
Step 3: Combine the results.
From left to right, the result is 113.
Therefore, the solution to the subtraction problem is , which corresponds to choice 4.
113
\( \begin{aligned} &105 \\ -& \\ &~~~~3 \\ &\underline{\phantom{776}} & \\ \end{aligned} \)
You'll need to borrow from the next column! For example, if you have 3-5, borrow 1 from the tens place to make it 13-5=8. Don't forget to reduce the tens digit by 1.
We start with the units column because if we need to borrow, it affects the columns to the left. Working right to left ensures we handle any borrowing correctly.
Use addition to check! Add your answer to the number you subtracted. If you get the original top number, your subtraction is correct: 113 + 135 = 248 ✓
The problem is set up in vertical format for you! This means the place values are already aligned correctly - units under units, tens under tens, hundreds under hundreds.
No! You only borrow when the top digit is smaller than the bottom digit in a column. In this problem (248-135), no borrowing was needed since 8≥5, 4≥3, and 2≥1.
