Since you are starting at -4,2 and going to 12, you are going in a positive direction, so your answer will be positive.
The formula is (final location) - (starting location)
= (1.2) - (-4.2)
= 1.2 + 4.2
= 5.6

Hi there...
You started off well, but you came to the wrong conclusion.
"(-4.2 + 5.6)=1.4"
While...
"(1.2 - -4.2)=5.4"
In other words...
"(1.2 - 5.4)=-4.2"
Question...: "How can I get to 1.2 form -4.2?"
Answer...: "(-4.2 + 5.4)=1.2"
I hope that cleared things up a bit?
Kind regards
