Answer 2

Sure! Let's break down each addition problem step by step:

1) 4 + 6 - (-3 + 8): - To add 4 and 6, we get 10. - To add -3 and 8, we get 5. - Finally, we subtract 5 from 10, which gives us a final result of 5.

2) 2.5 - (-3 + 5): - To add -3 and 5, we get 2. - Finally, we subtract 2 from 2.5, which gives us a final result of 0.5.

3) -4 + 2 - (-5 + 8): - To add -4 and 2, we get -2. - To add -5 and 8, we get 3. - Finally, we subtract 3 from -2, which gives us a final result of -5.

4) 4 + 7 - (-4 + 7): - To add 4 and 7, we get 11. - To add -4 and 7, we get 3. - Finally, we subtract 3 from 11, which gives us a final result of 8.

So, the results of the addition problems are: 1) 4 + 6 - (-3 + 8) = 5 2) 2.5 - (-3 + 5) = 0.5 3) -4 + 2 - (-5 + 8) = -5 4) 4 + 7 - (-4 + 7) = 8
