Answer 3

To calculate the expression 2.1 + 4.8 + (-3.8) + 2.1 + (-7.9) + 4.9 - (-2), you can follow these steps:

1. Add the positive numbers: 2.1 + 4.8 + 2.1 + 4.9 = 13.9
2. Add the negative numbers: (-3.8) + (-7.9) = -11.7
3. Subtract the result from step 2 from the result from step 1: 13.9 - (-11.7) = 13.9 + 11.7 = 25.6

So, 2.1 + 4.8 + (-3.8) + 2.1 + (-7.9) + 4.9 - (-2) equals 25.6.
