Subtract 314 minus 126: Vertical Format Solution

$\begin{aligned} &314 \\ -& \\ &126 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, we'll perform vertical subtraction as follows:

We'll align the numbers by their place values:
$314$
$- 126$

Start with the rightmost column (the units place):

• Units Place: $4 - 6$ requires borrowing because 4 is less than 6. Borrow 1 from the tens column in 314, turning it into 10, leaving 0 in the tens place. Now, $14 - 6 = 8$.

• Tens Place: After borrowing, $0 - 2$ also requires borrowing from the hundreds column. Borrow 1 from the hundreds column, leaving $2$ in the hundreds place. Now, $10 - 2 = 8$.

• Hundreds Place: Subtract as normal, $2 - 1 = 1$.

When we put it all together, the result is:

• Hundreds: $1$

• Tens: $8$

• Units: $8$

Therefore, $314 - 126 = 188$.

The solution to the problem is $188$, which matches choice $4$.
