-- 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.
Your question does not make sense. It would probably be interpreted as a + = ++a ---a
A plus + a plus is a plus.

Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.
A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).
= a minus

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
If something plus and minus something else make two then the initial value must be 2.
NO!!!! Here is a table for multiplication/division of 'double (+/-) signs.'. (+)(+) = (+) (+)(-) = (-) (-)(+) = (-) (-)(-) = (+) Sometimes in higher level maths, you can have triple signs. Here is the table. (+)(+)(+) = (+)(+) = (+) (+)(-)(-) = (-)(+) = (-) (-)(+)(+) = (-)(+) = (-) (-)(-)(-) = (+)(-) = (-) It is irrelevant on the position of the 'sign'. NB If no sign is given, then read it as positive (+).
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

Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.
+/- means that the answer can be either a positive(+) number or a negative(-) number. e.g. the sqrt(4) = +/- 2 Because +2 x +2 = 4 & -2 X -2 = 4 Similarly for any other square root values.
Shift-Option-Plus (+) will produce the ± symbol on a Mac.
6 plus 4 minus 2 plus 2 minus 3= 7 :)
