Solve Vertical Subtraction: 376 minus 136

Q: What if I need to borrow from the next column?

In this problem, no borrowing is needed because each digit in 376 is greater than or equal to the digit below it. When borrowing is needed, take 1 from the left column (making it 10 in the current column) before subtracting.

Q: Why do we start from the right side?

We start with the ones place (rightmost) because if we need to borrow, it affects the columns to the right. Working left-to-right would create confusion with borrowing!

Q: How can I check if my subtraction is correct?

Use addition to check! Add your answer (240) to the number you subtracted (136). If you get the original number (376), your subtraction is correct!

Q: What does it mean when the top digit equals the bottom digit?

When digits are the same, like $ 6 - 6 $, the result is always 0. Don't forget to write the 0 in your answer - it holds the place value!

Q: Do I always get a smaller number when subtracting?

Yes, when subtracting positive numbers! The result (240) should always be smaller than what you started with (376). If it's bigger, check your work!

00:03 Each time we calculate subtraction of 2 digits, and then we place

00:06 We'll start by subtracting ones from ones, and place in ones

00:09 We subtract tens from tens, and place in tens

00:13 We subtract hundreds from hundreds, and place in hundreds

Understand the problem

$\begin{aligned} &376 \\ -& \\ &136 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

Step-by-step solution

To solve this problem, we'll use the standard algorithm for subtraction performed in a vertical format. Here are the steps:

Step 1: Write the numbers in vertical form, aligning the digits by place value, with 376 above 136.
Step 2: Begin subtracting from the rightmost digit (units place).
Units place: $6$ from $6$ . Resulting digit is $0$ .
Step 3: Move to the tens place, subtract $3$ from $7$ . Resulting digit is $4$ .
Step 4: Move to the hundreds place, subtract $1$ from $3$ . Resulting digit is $2$ .

Therefore, the calculation looks like this:

$\begin{array}{c} & 376 \\ - & 136 \\ \hline & 240 \\ \end{array}$

As such, the solution to this subtraction problem is $240$ .

Final Answer

240

Key Points to Remember

Essential concepts to master this topic

Place Value Alignment: Stack digits vertically by ones, tens, and hundreds columns
Right-to-Left Method: Start with ones place: 6 - 6 = 0, then work leftward
Verification Check: Add your answer to the subtrahend: 240 + 136 = 376 ✓

Common Mistakes

Avoid these frequent errors

Misaligning place values when stacking numbers
Don't write numbers randomly without aligning place values = wrong digits in wrong columns! This causes you to subtract hundreds from tens or ones from hundreds. Always align the rightmost digits first, then stack each place value column perfectly straight.
