hey mine to help

mathmale · Answer

Was that " +- " in  9+-0+x*9=  intentional or not?
Do you mean "plus or minus zero" or do you mean (+)(-)=(-)  ?

anonymous · Answer

the - is for negitive then + is plus

I understand that, but still need to know which of the twi interpretations I gave you is the correct one.  We need to remove the ambiguity here.

Altho I would have liked for you to have decided that for yourself, let's move forward with the assumption that you meant  (-)(+).  In that case,

9+-0+x*9=       reduces to 9-0+x*9.
This, in turn, reduces to 9+x*9.

Again, I'm unsure what you mean  by   x*9:  Did you mean exponentiation, as in $$x ^{9}$$ or did you mean x times 9 (multiplication)?
