Math symbol needed

In word,  click Insert -> Symbol
select the symbol

what is the name of that symbol in mathematics?

Any of these symbols:    ¿ ¿ ¿ I i

I mean "¿¿¿Ii"

¿¿¿Ii

i could not paste the symbols here.

You can always browse the char sets from installed fonts using the char map tool in system utilities.
Once you identify the symbol you're looking for, you can copy an paste it directly from the char map tool or use the related char code with the alt key pressed and the keypad.

It's not one of the standard characters in the character sets. You won't be able to use it in many places even if you find it. It's better to come up with one that you use instead of it to mean the same thing.

What are you trying to use it to mean? There might be a standard symbol that others use for it.

To enter the desired symbol, while holding the ALT key down enter 842 on the numeric keypad.

Note: If using a laptop put the keyboard into number lock mode (by pressing the "Num Lk" key) and enter the numbers using the numeric keypad by pressing FN+ALT+digit where digit is any of the keys M=0, J=1, K=2, L=3, U=4, I=5, O=6, 7=7, 8=8, or 9=9. Do not use the regular number keys at the top of the keyboard. To turn off number lock press the "Num Lk" key again. Number lock mode is usually indicated with a lit "9" somewhere in the control light area.

If you want the symbol to stand on it's own enter a space before and after entering the symbol.

Usually you would need to do Alt+0842

You don't need the leading zero.

That's not exactly the character you are looking for. It's designed to float above other characters, but it might be enough. It's in the standard set so most things will print it. You can't use it on EE though.

Actually, I didn't need the 0. Don't know why it looked like I did at first.

>That's not exactly the character you are looking for. It's designed to float above other characters, but it might be enough.

I can't find one that isn't an accent. That's why I suggested using two spaces to allow separation from other characters if desired.

Thanks for all the help.  Still not finding it though I should rephrase.

I am looking for the opposite of THIS ˜ SYMBOL, not this ~ symbol.  

It would be a ˜ symbol with a horizontal line through it.

oh my.  It's not pasting here even.  It is the double ˜ mark and needs a line through it.  Even a picture of it would get us part way.  I am trying to illustrate that there is a balance of numbers.  The positive integers add up to equal the negative integers.

Horizontal? You must mean vertical. And do you really mean double tilde as in an equal sign?

Kevin

As in code 844?

Kevin

Kevin, thanks.  

Double tilde with a diagonal line through it.  That's exactly it.  That's what I am looking to find.

Have you tried Microsofts Mathmatics Add-in? It's a free download and has several formulas and symbols. You can get it at this link:

As in "sort of not equal to" ;-)

Hmmm...not sure there is such a symbol.

Still looking...

Kevin

When I need a character, I usually go to http://www.alanwood.net/ and see if I can find it or it's name there.  Look at the Unicode and HTML Entities pages.

Do you see it here?

Suggestion 1: Use Paint program and create the image of it manually and paste it in your document

Suggestion 2: If you can get the digital version of your text book (where you see the symbol) just copy paste from it.

Let me know what chapter is it in Mathematics? this way search the concept online and somewhere you see it.

>I am trying to illustrate that there is a balance of numbers.  The positive integers add up to equal the negative integers.

How about this:

Congruence is represented by 2 different symbols as in http://en.wikipedia.org/wiki/List_of_mathematical_symbols
(search for congruence in it)

In the first link above you can see the not congruence symbol with the diagonal on it.

"congruence"  is "isomorphic" in mathematics  (if i am correct)

Isomorphic is the structural congruence of two sets. This is a sum zero situation...I think ;-)

I just hope there are no square roots of negative one in there. That crap makes my head hurt.

From what you are describing, this is the correct symbol but it means "not approximately equal to":

¿ perfect Kevin.  It was there

Great exhaustive list, and with index numbers no less!
