Solve Three-Digit Addition: 574 + 313 in Vertical Format

$\begin{aligned} &574 \\ +& \\ &313 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this vertical addition problem, follow these steps:

• First, write the two numbers vertically, aligning them by their place values:
  $\begin{aligned} &574 \\ +& \\ &313 \\ \end{aligned}$
• Add the digits in the ones column (far right):
  - 4 + 3 = 7
• Proceed to the tens column (middle):
  - 7 + 1 = 8
• Finally, add the digits in the hundreds column (far left):
  - 5 + 3 = 8

Thus, the sum of 574 and 313 is $887$, which matches the correct answer choice.
