Question

-0,69+(-1.31)+(+1.31)-5.3

Answer 1

   -0,69+(-1.31)+(+1.31)-5.3  = -5.99

Answer 2

1) -0.69+(-1.31)=-2 2) -2+1.31 =-0.69 3) -0.69-5.3=-5.99

Answer 3

-0.69 + (-1.31) + (+1.31) - 5.3

First, we can combine like terms: -0.69 - 1.31 + 1.31 - 5.3 = (-0.69 - 1.31 + 1.31) - 5.3 = -0.69 - 5.3

Now, we can add -0.69 and -5.3: = -0.69 - 5.3 = -5.99

So, the final answer is -5.99.
