Want a 'does not equals' sign? Put a slash in between two equals signs, like so.
=/=
Hope this is helpful.

You've got the wrong code for minus. 45 is a hyphen, not a true minus sign. It's too short, plus in some fonts it can be on an angle (which clearly a minus sign shouldn't be).
The true minus sign is alt+0150
hyphen: -
minus sign: –
Thanks,
Ariel

Correction to my comment above: It's not alt-150, which is an en-dash. It's unicode 2212, which I don't think is accessible with the Windows alt-keypad trick. So if you want a true minus, just copy and paste from here:

If these dont work, just go to your Start menu, click RUN , type in charmap, and click OK and you can get all the codes, and you can copy&Paste them :D
Btw, this isnt a trick =.=

Well, many of you can't seem to get the codes to work. I have a little tip for you.
Copy-Paste still works it's magic on Alt symbols.

Is there a way to do the nth power of a radical. Like the 4th root? (4)√xy . That is how I am doing it now but I wonder if there is a code to doing it correctly?

Very helpful resource. I’m a new reader on your blog, I just want to let you know that I really appreciate the information that you share here about WP. Keep up the good work.

That list of ALT codes is dependent on the particular code page that the computer is using. Code page 850 is common in the U.S.A.; code page 437 is common in the U.K. The code pages are not the same. ALT 185 and ALT 179 being two examples.
You should mention this code page dependence prior to that list - and tell everyone what code page it refers to.

I need to type math symbols frequently enough to want to use ALT codes, but not frequently enough to memorize them, so I like the idea of your reference page, but it doesn't seem to quite be correct.
ALT+240 gives me what charmap calls a 'Latin eth' and ALT+246 gives me an obelus.
