How to write math in an email
By Murray Bourne, 16 Sep 2009
Perhaps you're a student and you need to ask your teacher a question about your math homework. You go to type it in an email but have trouble when you get up to the square root, fraction, integral and summation signs. Greek characters pose even more of a challenge.
When your teacher receives your mail, she has trouble reading what you are asking about and has to ask you to clarify it.
I've developed a "math in email" application that aims to make the process easier. It's built on ASCIIMathML, which displays good looking math using normal fonts (in Firefox) or images (in other browsers).
I've updated it so it now sends the mail directly so the recipient can read it in their email program (whereas before they had to click a link to see the contents of the mail).
Using this system, you can type simple commands to achieve math symbols in your email. The approach is similar to the way you enter math into a graphics calculator or a spreadsheet.
For example, a fraction can be typed using "/", as in: (a + b)/c, and it will display as a proper (vertical) fraction. There's just one trick - you need to enclose your math in opening single quotes (not apostrophes) like this:
`(a + b)/c`
A square root is simply: `sqrt(x+5)`
Superscripts (powers): `x^2`
Go try out the Math Mail system. You can send a mail to yourself to test it out (it will send a copy to you for your own records).
Feedback is welcome - did it work OK for you?

I use math to find discounted stock prices when buying. It has worked phenomonally. Im studying pre-calc on my own in hopes to continue upward as there is other calculations that require probability & calculus. Whatever problem my text or accompanying dvd cant help me with, I will ask you. Thanks. Vince
