if you have a problem like 9x-(-2x) is it like this:
9x+(-2x)
OR
9x+2x
OR SOMETHING ELSE?!
please and thank you SO MUCH!

In school they used to teach us to read the words...
If the words said "minus a minus"
. . . that meant plus
So your example 9X- (-2x)
is 9X minus a minus 2x
Which means
9X plus 2X
Which is 11X
Good luck,
Zah
