Answer 2

To calculate the expression (2.8 - 3.55) - (7.2 - 3.55) + (4.8 + 7.2 - 3.2), you can follow these steps:

1. Calculate the values inside each set of parentheses first:

   • Inside the first set of parentheses: 2.8 - 3.55 = -0.75
   • Inside the second set of parentheses: 7.2 - 3.55 = 3.65
   • Inside the third set of parentheses: 4.8 + 7.2 - 3.2 = 8.8

2. Now, substitute these values back into the original expression:

   • (-0.75) - (3.65) + (8.8)

3. Finally, perform the remaining arithmetic operations:

   • (-0.75) - (3.65) + (8.8) = -0.75 - 3.65 + 8.8 = 4.4

So, the result of the expression (2.8 - 3.55) - (7.2 - 3.55) + (4.8 + 7.2 - 3.2) is 4.4.
