Answer 2

Calculation A: 6.72 - 3.87 - (-3.6)

To solve this calculation, we can follow the order of operations, which is parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right).

The expression 6.72 - 3.87 - (-3.6) can be simplified as follows:

6.72 - 3.87 - (-3.6) = 6.72 - 3.87 + 3.6

Now, we can perform the addition and subtraction:

6.72 - 3.87 + 3.6 = 2.85 + 3.6 = 6.45

Therefore, the result of the calculation 6.72 - 3.87 - (-3.6) is 6.45.

Calculation B: 27.14 - 30.21 - 2.4

To solve this calculation, we can again follow the order of operations.

The expression 27.14 - 30.21 - 2.4 can be simplified as follows:

27.14 - 30.21 - 2.4 = -3.07 - 2.4

Now, we can perform the subtraction:

-3.07 - 2.4 = -5.47

Therefore, the result of the calculation 27.14 - 30.21 - 2.4 is -5.47.
