Answer 2

Let's solve the given expressions:

1. -0.37 + (0.37 + (-5.5)): To solve this expression, we start by calculating the value inside the parentheses first: 0.37 + (-5.5) = -5.13

Now we substitute this value back into the original expression: -0.37 + (-5.13) = -5.50

Therefore, -0.37 + (0.37 + (-5.5)) equals -5.50.

2. -17.8 + (9.9 + 17.8): Again, we begin by calculating the value inside the parentheses: 9.9 + 17.8 = 27.7

Now we substitute this value back into the original expression: -17.8 + 27.7 = 9.9

Therefore, -17.8 + (9.9 + 17.8) equals 9.9.
