Vertical Subtraction: 3-digit subtraction with the regrouping of tens

To solve this problem of subtracting 29 from 186 using vertical subtraction, we will follow these steps:

• Step 1: Set up the subtraction problem by writing 186 above 29, aligning them based on place value (units, tens, hundreds).
• Step 2: Begin subtracting from the rightmost column (units).
• Step 3: If the top digit in a column is smaller than the bottom digit, regroup from the next left column.
• Step 4: Write the result beneath the line for each column.

Let's work through the subtraction problem:
186
- 29
--------

Step 1: Start with the units column: $6 - 9$. Because 6 is less than 9, we need to regroup.

Step 2: Look at the tens column. From the tens column represented as 8, we borrow 1 ten (equivalent to 10 units), converting 8 tens to 7, and adding 10 to the units column, making it 16.

Step 3: Now subtract in the units column: $16 - 9 = 7$.

Step 4: Move to the tens column. After borrowing, we have 7 tens minus 2 tens: $7 - 2 = 5$.

Step 5: Finally, subtract the hundreds column: $1 - 0 = 1$, as no borrowing was needed here.

Combine these results from each column to obtain the final answer: 157.

Therefore, the solution to the problem is $157$, which matches choice 3 from the provided options.

To solve the subtraction problem $234 - 26$ using vertical subtraction, we follow these steps:

• Step 1: Align the numbers by place value.
  234
  - 26
  $\underline{\phantom{776}}$

• Step 2: Subtract the digits starting from the right (units place):
  - Subtract the digits in the units place: Since 4 < 6, we need to borrow. Borrow 1 from the tens place of 234 (making the tens digit 2 into 1), turn 4 into 14 in the units place.
  - Now, $14 - 6 = 8$.

• Step 3: Move to the tens place:
  - Because we borrowed 1, the top digit in the tens column is now 2 (originally 3, but reduced to 2 because we borrowed 1 for the units place).
  - Subtract the digits in the tens place: $2 - 2 = 0$.

• Step 4: Move to the hundreds place:
  The hundreds place is straightforward as there's no borrowing involved and the top digit is still 2, so $2 - 0 = 2$.

Putting it all together, the calculation becomes:
$234$
$- 26$
$\underline{208}$

Therefore, the solution to the problem is $\textbf{208}$.

To solve this problem, we need to perform the vertical subtraction of the numbers given:

• 357 as the minuend

• 19 as the subtrahend

Let's go through the steps to find the result:

Step 1: Align the numbers vertically based on their place values:
      357
-     19
  ______

Step 2: Start subtracting from the rightmost digits.
- Subtract the units place: $7 - 9$. Since 7 is smaller than 9, we need to borrow 1 ten (10) from the tens column.

Step 3: After borrowing:
- The 7 becomes 17.
- The tens column changes from 5 to 4.

Now, subtract: $17 - 9 = 8$.

Step 4: Move to the tens place:
- Subtract: $4 - 1 = 3$.

Step 5: Move to the hundreds place:
- There is no need for regrouping here, so simply bring down the 3.

The subtraction is complete, giving us:
       338

Therefore, the solution to the subtraction problem is $338$. This corresponds to choice 2 in the provided answer choices.

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

• Step 1: Set up the numbers for vertical subtraction.

• Step 2: Perform subtraction starting from the rightmost digit (units place).

• Step 3: Apply regrouping whenever the top digit is smaller than the digit below.

Now, let's work through each step:
Step 1: Write the numbers in vertical format aligning by place value:

$\begin{array}{c} 482 \\ - 65 \\ \hline \end{array}$

Step 2: Subtract the digits in the units place:$\quad 2 - 5$. Since 2 is smaller than 5, we need to regroup.

Regrouping: Borrow 10 from the tens place, making 2 become 12. The 8 in the tens place decreases by 1 to 7.

$\begin{array}{c} 4 &amp;\cancel{8}7 \, &amp;12 \\ -\ \ &amp;6&amp;5 \\ \hline \end{array}$

Subtract in the units place: $12 - 5 = 7$.

Step 3: Move to the tens place: Now subtract $7 - 6 = 1$.

Finally, subtract in the hundreds place: As there’s no digit to subtract from 4, it remains $4$.

Therefore, after performing the subtraction, the result is:

$\begin{array}{c} 417 \\ \end{array}$

Thus, the solution to the problem is $417$, which corresponds to choice 2.

Therefore, the solution to the problem is $417$.

To solve this problem, we'll use vertical subtraction, often referred to as column subtraction. The given problem is:

$\begin{aligned} &amp;577 \\ -&amp; \\ &amp;~~18 \\ \underline{\phantom{776}} &amp; \\ \end{aligned}$

We'll perform the subtraction step by step:

• Step 1: Subtract the rightmost column (units):
  - From 7, subtract 8. Since 8 is larger than 7, borrow 1 from the tens column of 577.
  - Borrowing makes the 7 into 17 in the units column and the 7 in the tens column into 6.

• Step 2: Subtract in the tens column:
  - From the borrowed 6 in the tens column, subtract 1, giving us 5.

• Step 3: Subtract the hundreds column:
  - There is no borrowing needed here. Simply bring down the 5 as there is no corresponding number to subtract from the subtrahend, yielding 5.

Hence, the calculation becomes:

$\begin{aligned} &amp;5 &amp;\cancel{7}6 &amp;&amp;17 \\ - \\ &amp;&amp;1 &amp;&amp;8 \\ \overline{\phantom{2342}} \\ \end{aligned}$

Therefore, the solution to the subtraction problem is $559$.
