We are Missing Y.
What is the opposite of Addition?

Answer 8

subtraction

Answer 9

Yep! See, we would do addition, But since we are doing Negative Numbers we still must do subtraction. So now we do 1.8 - 0.6 INSTEAD of 1.8+0.6. What do we get?

1.2

Answer 11

Very good job, Now turn THAT number into a negative number. Then Plug -1.2 into Y. What do we get when we check our work ? :)
