Answer 1

Ответ:

1)-5,5+6,7=1,2

2)-5,5-6,7=-12,2

3)5,5+6,7=12,2

4)-5,5+(-6,7)=-5,5-6,7=-12,2

Answer 2

It seems like you want to perform a series of arithmetic calculations with the numbers provided. Let's break it down step by step:

1. -5.5 + 6.7 = 1.2
2. 1.2 - 5.5 = -4.3
3. -6.75 + 5.5 = -1.25
4. 5.5 + 6.7 = 12.2
5. -5.5 + (-6.7) = -12.2

So, your calculations are as follows:

-5.5 + 6.7 - 5.5 - 6.75 = -4.3 - 1.25 = -5.55 5.5 + 6.7 - 5.5 + (-6.7) = 12.2 - 5.5 - 6.7 = 0.0 - 6.7 = -6.7
