Answer 2

Let's solve each of these arithmetic operations step by step:

1. -3 + 7 - 2 + 1 = (group the terms with positive and negative signs) = (-3 + 1) + (7 - 2) = -2 + 5 = 3

2. -4 + 3 - 5 + 4 = (group the terms with positive and negative signs) = (-4 + 4) + (3 - 5) = 0 - 2 = -2

3. 5.33 + 2.2 = 7.53

4. 0.125 + (-2 3/8) = (convert the mixed fraction to a decimal) = 0.125 - 2.375 = (subtract the decimals) = -2.25

So, the results of the given arithmetic operations are:

1. -3,7-2,1 = 3
2. -4,3-5,4 = -2
3. 5,33+(2,2) = 7.53
4. 0,125+(-2 3/8) = -2.25
