Answer 1

Welp me idk 😐 anything I suck at mathematics

Answer 2

Of course you do, if you take a minute to think.
how you find the change going from 4 to 10?
You subtract 4 from 10, right? It changed by 6
So, in this case, the change is
-2 - (-10) = +8

and why do you put your minus signs on a separate line? So annoying.
