Step-by-Step Solution

To solve this vertical addition problem, let's break down each step:

Step 1: Align the numbers for vertical addition:
    742
+  258
Step 2: Add the units column (rightmost digits):
2 + 8 = 10, write down $0$ and carry over $1$ to the tens column.
Step 3: Add the tens column, including the carry:
4 + 5 + 1 (carry) = 10, write down $0$ and carry over $1$ to the hundreds column.
Step 4: Add the hundreds column, including the carry:
7 + 2 + 1 (carry) = 10, write down $0$ and carry over $1$ to the thousands position.
Since there is a carry in the thousands position, write down $1$ as the leading digit.

Therefore, the sum of $742$ and $258$ is $1000$ .
