Question

-3,2-(-1,9)+(3,1)+7,8

Answer 1

-3.2+1.9+3.1+7.8=9.6

Answer 2

To calculate the expression, you need to perform the operations step by step:

1. Subtract (-1,9) from (2, -3): (2, -3) - (-1, 9) = (2, -3) + (1, -9) = (2 + 1, -3 - 9) = (3, -12)

2. Add (3, 1) to the result of the previous step: (3, -12) + (3, 1) = (3 + 3, -12 + 1) = (6, -11)

3. Finally, add (7, 8) to the result: (6, -11) + (7, 8) = (6 + 7, -11 + 8) = (13, -3)

So, the final result of the expression is (13, -3).
