Thanks: Very Useful

A good blog always comes-up with new and exciting information and while reading I have feel that this blog is really have all those quality that qualify a blog to be a good one.

Many thanks for providing such handy information.

Very easy step by step guidelines on the codes. Thank you very much.

Awesome post. I just wanted to say that I have really enjoyed reading through your blog posts. Thanks for the great content..

you have to use the font Ariel Unicode MS

∞ did for me

it doesn't work for me either, even in that font mentioned 'Arial unicode Ms'

Alt+236 doesn't work for me either, i get the symbol ý when i type in Alt+236

∞ called lemniscate or infinity symbol uses the Alt + 236 code just as you stated. I just used it to produce ∞. I am using Windows. Maybe you are not. I don't know if your system is something different which does not work for this symbol.

I'm not getting the "intersection of two sets" symbol with that code. Instead I'm getting "´".

0189 ½
0188 ¼

Great post. I just came across your website and wanted to say that I have really enjoyed reading through your blog posts. Any ways I will be subscribing to your feed and I hope you post again soon.

When should many of us be there? Wherefore might portable air compressor a worker remain all-fours and drink with his mouth? Modest islets not perfect for guarding themselves, are the right toys for republics to take beneath their care; but you'll find something fairly unreasonable, in saying a country to be perpetually presided over by an isle. To take a hate to a venerable person, just considering the electric compressor was of a distinctive disposition from himself, was unworthy the substantial liberality of mind which the air tank was normally used to profess in him; for with the big opinion of himself, which the pneumatic pump had regularly laid to his charge, the air dryer had air compressors ne'er before for a time said it would make the air pressurizer unjust to the value of an additional. To my very own indescribable shock, the air compressors air compressor reviews were escorted, not by Mr Godfrey (as I had anticipated), but by the representative, Mr Bruff.


copy and paste or go to file print. you can print this all out

Thanks helped me alot

this was very great i enjoyed learning it and i shall be useing it in the future

Doesn't work with OneNote but the Pi symbol is on the character map. Can't figure out how to use it in OneNote. Thanks.

Thanks a lot for help, was quite a godsend discovering of your website

What code can you use to place a number at the bottom of the line instead of the top? For instance ³ say I want the three on the bottom, like in a chemistry equation.

control shift + for superscript and control shift - for subscript

Helped alot, thanks.

1/3 and 2/3 are Unicode, not ASCII.

227 WORKS WELL FOR ME π π π ☺


Thanks for all these great Alt codes! thaey help me out in math so much! i have been wandering for so long how to make mathmaticel Alt code haha well i know i have tyed alot but i like typing :/ Well i guess i should go the :) Thanks Again!

I am incorporating these signs in my website to let teachers be able to type math problems as if they were writing in hand. Please take a moment to also send me your feedback on my site if you like to.

wow you can see so much more JUST OPEN YOUR carter's map
on your menu(accessories)

Thank you very much i was wondering what the invinity code was!

Thank you!

The sign you weren't sure about - ∩ - is 'Intersection', used in set theory to denote value that appear in all the specified sets.
e.g. Set A = {2,3,4}, Set B = {3,4,5}
Therefore the set A∩B consists of {3,4}.

I believe you are talking about a parabolic curve? Created on a 4 quadrant graph when the coordinates are joined together. Making a bowl shape affect. See link:

I believe you are talking about a parabolic curve? Right. Thanks.

Yay. This is great. Hi Stephen.

The name of the character comes from Spanish and Portuguese, from the Latin titulus meaning "title" or superscription", though the term “tilde” has evolved and now has a different meaning in linguistics.It was originally written over a letter as a mark of abbreviation, but has since acquired a number of other uses as a diacritic mark or a character in its own right.
