Answer 2

Let's solve the expressions step by step:

1. 27.56 - 36 - 27.56 - (-12)

Step 1: Subtract 36 from 27.56 27.56 - 36 = -8.44

Step 2: Subtract 27.56 from the result of step 1 -8.44 - 27.56 = -36

Step 3: Add 12 to the result of step 2 (remember that subtracting a negative number is the same as adding its positive counterpart) -36 - (-12) = -24

So, the result of the expression is -24.

2. 39.126 - 12.1 + 18 - 21.026

Step 1: Subtract 12.1 from 39.126 39.126 - 12.1 = 27.026

Step 2: Add 18 to the result of step 1 27.026 + 18 = 45.026

Step 3: Subtract 21.026 from the result of step 2 45.026 - 21.026 = 24

So, the result of the expression is 24.
