Step-by-Step Solution

To solve this problem, we'll perform vertical addition. Here are the steps:

Step 1: Write the numbers 999 and 185 vertically, aligning them by the rightmost digit.
Step 2: Begin adding from the rightmost column.

Let's start with the units column:

Next, the tens column:

Finally, the hundreds column:

The hundreds digits are 9 (from 999) and 1 (from 185), plus the carry-over value 1.
Add them: $9 + 1 + 1 = 11$ .
Write down 1 and carry over the 1 to form a new thousands column.

Since there's nothing else to add in the thousands column, write down the carry-over as 1.

Therefore, the sum of 999 and 185 is $\mathbf{1184}$ .
