Solve Vertical Subtraction: 357 minus 19 Step-by-Step

$\begin{aligned} &357 \\ -& \\ &~~19 \\ &\underline{\phantom{776}} & \\ \end{aligned}$$$$$

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.
