Answer 2

It looks like you've provided two sets of numbers separated by semicolons. If you'd like to perform addition separately for each set, I can help you with that. Let's break it down:

Set 1: 45 + 21 + 15 + 49 = 130 Set 2: 56 + 25 + 45 + 24 = 150

So, the results are: Set 1 sum: 130 Set 2 sum: 150
