The key should be on the top row of your keyboard on the right hand side on the same key as the = sign.
To get the plus (+) symbol press control and the key with both = and + on it.
Should be ~ to press the "Shift" key and the key with the (+) and (=) sign together or just use the number pad on the right side of the full keyboard with the (+) sign.

The plus sign (+) should be at the top of your keyboard. If there is another symbol below it on the same key, then you need to hit "shift" and the "+" sign so it won't print the other symbol that's below it. The minus sign ( - ) should also be at the top of your keyboard. The same instructions apply to it as to the + sign.
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 (+).
The person who invented the plus sign is the same as the minus
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).
Shift-Option-Plus (+) will produce the ± symbol on a Mac.
The button to the immediate right of the 0. no shift.
If you mean the ADDITIVE INVERSE, change the minus sign to a plus sign. (And if you see a plus sign, you change it to a minus sign.)
It indicates "plus or minus".
The minus sign (-) is typically located on the keyboard in two places: on the top row of number keys, just to the right of the number 0, and on the numeric keypad (if available) as a separate key, usually near the number 0 or on the same key as the plus sign (+). It can also be used in combination with other keys for functions such as shortcuts in certain applications.
To find the additive inverse of any number, just change the plus sign (or no sign) to a minus sign, or (as in this case), if there already is a minus sign, change it to a plus sign (or no sign).
