You would subtract. For example, if you have 5-7, you would subtract the two like normal. And if you have 5+(-7) you would also subtract, because adding a negative number to a positive is the same as subtracting.
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
A minus and a minus makes a plus A plus and a plus makes a plus A minus and a plus or plus and a minus makes a minus 7 - -2 is a minus and a minus Therefore the answer is 7 + 2 = 9
No, it becomes a plus, since minus x minus = plus
Minus...
3x minus 4f=? x=3 f=4
They are called plus and minus - no difference there!
= a minus
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
yes
What are you trying to get? (0,0) works for roots Hope I helped, Y.a.r.o.
-- If they're being multiplied or divided, then they make a minus. -- If they're being added or subtracted, then they can make either a plus or a minus. It depends on which one is bigger.
If something plus and minus something else make two then the initial value must be 2.

A plus + a plus is a plus.

If the question was a+8-4=16 what is a? you have to work backwards and change the plus to minus and minus to plus... 16+4-8=a, a=12 If the algebra question was a little bit more complicated like 2n+6= 20, that is the same as 2xn+6=20. Like before, we have to work backwards so (20-6):2=n, n=7
