Solve 677 + 234: Three-Digit Addition in Vertical Format

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

• Step 1: Write the numbers one under the other, aligning their digits by place value.

• Step 2: Add the digits from the rightmost column to the left, carrying over where needed.

Detailed Steps:
Step 1: Begin with the units place. Add the digits in the units column: $7 + 4 = 11$. Write down 1 in the units column and carry over the 1 to the tens column.

Step 2: Move to the tens column. Add the digits along with the carried over value: $7 + 3 + 1 = 11$. Again, write down 1 in the tens column and carry over the 1 to the hundreds column.

Step 3: In the final hundreds column, add: $6 + 2 + 1 = 9$. Write down the 9 in the hundreds column as there are no more digits to add.

The final result by putting all these together is: $911$ .

Therefore, the sum of 677 and 234 is$911$
