press function (Fn) + P
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 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 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".
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).
