All the maths codes are very important.very nice website for the students who want to learn the maths. i want to asked you that is there any formula for the trigonometric.

Thank you for these codes
I am writing a site for my son and they are very useful

Want a 'does not equals' sign? Put a slash in between two equals signs, like so.


Hope this is helpful.

Is there no shortcut for the not = sign?

How can i write summesion ?

it doesn't work on my keyboard why ??

amazing very informative
perfect list
thanks for sharing.

Yah, you are right. I love it very much. Thanks.

is there a ratio sign?


I liked your series of articles.
It even helped me to solve my Vedic Maths system problems.

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: –


mathematical codes in one single blog, thanks dude for sharing this wonderful post.

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 =.= is super, bookmarked!

Good Job..:)

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 interesting !!

Thank you for always providing great content

Are there any other fractions? 2/3, 7/8 etc.

Alt-236 = ý for me not infinity, even in Arial Unicode MS.

Nice post about ALT Codes - Alt Codes for Maths / Mathematics. I am very impressed with the time and effort you have put into writing this story. I will give you a link on my social media blog. All the best!

I think this blog is very nice and informative, thanks for posting here

the alt 236 is not working for me either. Did somebody find a new key that would do it?

Thankyou very much

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?

Is there an Alt Code for the symbol that represents the mathematical relation "is an element of"?

Thanks in advance.

For powers I generally utilize the superscript option for the particular font I use in the document.

nice code, hope use fine, thanks men

This page is great!! Thanks a lot.

awesome;thanks (:

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.

Alt codes ☺

Awesome post .Very easy step by step guidelines on the codes.thank you!!

Thank you for this helpful site! MR
