± You can go to the "Character Map" on your PC and find it there. You can find all sorts of math symbols on there. Click once on the symbol and you should get the keyboard shortcut for that symbol. The plus/minus sign is something like "Alt + 241" (Thank You, MamaMia! ;-) It's been years since I touched a PC!) If you're on a MAC, just type "Shift + Alt/Option" and the "+/=" key ± Hope I helped!
Plus and minus in c++?
± is an extended ASCII set, as you can see here: http://www.asciitable.com/ And it isn't completely portable, since someone can use a different character set in their DOS/Windows environment that would not allow it to show up the same on all machines. In order to output it, you could do this: printf("%c", 241); Or press and hold the ALT key, and on the number pad press the following keys (while still holding down the ALT key), '2', '4', and '1'. When you release the ALT key, it will appear in your code (a lot of editors do that anyway).

I don’t remember where I read it, or all the details (or even if it’s true or not), but here goes:When someone owed money to a money lender, the lender had a book with a list of the names and the amount they owed him. It looked something like this:John Doe - 500When the money was returned, the lender added a slash over the hyphen to note that:John Doe + 500And thus the plus sign was invented

It is very common to have a patient with multiple comorbid conditions that can all contribute to their illness.
Should I add a plus or a minus sign?
That depends on the sign of [math]x[/math].If [math]-1 \leq x < 0[/math] then[math]\frac{\sqrt{x+1}}{x} = -\sqrt{\frac{x+1}{x^2}}[/math]if [math]x>0[/math] then[math]\frac{\sqrt{x+1}}{x} = \sqrt{\frac{x+1}{x^2}}[/math]So the general answer is[math]\frac{\sqrt{x+1}}{x} = \sgn(x) \sqrt{\frac{x+1}{x^2}}[/math].Note that [math]x<-1[/math] doesn't make sense unless you allow complex numbers. [math]x=0[/math] is not allowed in any case.
What's the name for "plus or minus" (±)?
I think that what you are asking is—if the “symbol” has a special “name”—NOT what it means, which is almost what everyone else is answering. For example, what would a typesetter from the 1800’s call it?It should have a special name. We have one for #, which has been called the “pound sign” in the past and has now morphed into “hash” and, due to the popularity of Twitter, “hashtag.” The asterisk, *, has morphed into “splat.” The exclamation point, !, is now “bang.” We even have had special names for diphthongs.So what about our “special name” for the plus-minus sign? None. It’s just “the plus-minus sign.”Gee. How boring.
