# Is there a way to put a plus minus sign in an answer?

##### 1 Answer

#### Answer:

Do you mean a *minus-plus* sign?

#### Explanation:

Since you already know how to write a *plus-minus* sign, *minus-plus* sign, which looks like this

From what I can tell, you can't really write this symbol in the editor.

Classic MathJax has the functions **\pm** for the plus minus sign which works here as well

without the hashtags\pm2

with the hashtags

#\pm2#

and **\mp** for the minus plus sign, which does not work in the editor

without the hashtags\mp2

with the hashtags

#\mp2#

However, you can improvise a little by using the **stackrel()()** function, which allows you to stack symbols or characters (text) on top of each other.

For example, you can write

without the hashtagsstackrel("---")(+)

with the hashtags

#stackrel("---")(+)#

It's not perfect, but it does the job :D.

**ADDENDUM**

I found a better way of writing the minus plus sign

without the hashtagsstackrel(_)(+)

with the hashtags

#stackrel(_)(+)#

I personally think the first option looks better

#stackrel("---")(+)2" "color(green)(sqrt()) " "# versus#" "color(red)(cancel(color(black)(stackrel(_)(+)2)))#

**ADDENDUM II**

Here's another way of writing the minus plus sign--this one is brought to you by Ernest Z.

The plus-minus sign is Unicode character 2213, so you can write in MS Word first by using writing **2213** followed by **ALT + X**.

Simply copy/paste the sign to the editor. It will look like this

without the hashtags∓2

with the hashtags

#∓2#

I think we may have found the best version

#stackrel("---")(+)2 " "# #" "color(green)(ul(color(black)(∓2))) " "color(green)(sqrt()#

**ADDENDUM III**

Here's yet another way of writing the minus-plus sign, this time brought to you by NickTheTurtle!

without hashtagsbar("+")2

with hashtags

#bar("+")2#

I think that this version gets the job done + it has the added bonus of being easier to add to the answer!

#stackrel("---")(+)2 " "# #" "∓2 " "# #" "bar("+")2#
