Answer 3

To calculate the expression (-3.14 + 2.71) - (-4.7 + 1.8), you can follow these steps:

1. First, simplify each set of parentheses:

   (-3.14 + 2.71) = -0.43 (-4.7 + 1.8) = -2.9

2. Now, you have the expression -0.43 - (-2.9).

3. To subtract a negative number, you can change it to addition and reverse the sign:

   -0.43 + 2.9

4. Now, add the two numbers:

   -0.43 + 2.9 = 2.47

So, the result of the expression (-3.14 + 2.71) - (-4.7 + 1.8) is 2.47.
