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
A plus with a minus under it means "plus or minus" in math.
No, it becomes a plus, since minus x minus = plus
Minus...
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.
In addition and subtraction, if the plus sign is larger than the minus sign, then it's a plus. For example: +10 minus -20 = -10 If the plus sign is smaller than the minus sign, the answer will be a minus. For example: -10 minus + 20 = -10 In multiplication, if you have 2 plus signs, the answer will be a plus sign. If you have 2 minus signs, the answer will be a plus sign then, too. But if you have a plus and a minus sign, then the answer will be a minus. For example: +5 x + 2 = +10 -5 x - 2 = +10 -5 x +2 = -10
A plus + a plus is a plus.
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
