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 (+).
Minus 8 plus 6 equals -2.

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).
It is plus 4
3 + 6 - 2 + 14 - 3 + 2 = 20
-2 times -2 = plus 4 since minus times minus is plus
