00:03 Each time consider combining 2 digits, and then place

00:06 Let's start by combining ones with ones

00:09 Place the ones, and remember 1 to carry up

00:12 Combine tens with tens, remember to add 1 to the calculation

00:19 Place the tens in the tens place, and carry 1 to hundreds

00:23 Place 0 in the missing digits

00:29 Combine hundreds with hundreds, and place in the appropriate position

Step-by-Step Solution

To solve this problem, we'll perform vertical addition for the numbers 99 and 25:

Step 1: Add the ones place digits:
The ones digit of 99 is 9, and the ones digit of 25 is 5. Adding these together: $9 + 5 = 14$ . We write down 4 and carry over the 1.
Step 2: Add the tens place digits, including the carryover:
The tens digit of 99 is 9, and the tens digit of 25 is 2. With the 1 carried over, we compute: $9 + 2 + 1 = 12$ . Since there's no place to the left of tens for a third digit in this case, the whole number 12 is written in the tens and hundreds place.

Combining these, the sum is put together as 124.

Therefore, the solution to the problem is $124$ .
