Solve 614 + 290: Three-Digit Column Addition Practice

$\begin{aligned} &614 \\ +& \\ &290 \\ &\underline{\phantom{776}} & \\ \end{aligned}$

To solve this problem, let's perform vertical addition following these steps:

Step 1: Add the unit digits (rightmost column):

• $4 + 0 = 4$

Step 2: Add the tens digits (middle column):

• $1 + 9 = 10$
• Write $0$ and carry over $1$ to the hundreds column.

Step 3: Add the hundreds digits (leftmost column), including the carryover:

• $6 + 2 + 1 = 9$

The sum of the numbers $614$ and $290$ is $904$.

Therefore, the solution to the problem is $904$.
