After a question on this the other day I thought I would start a thread with instructions on how to place mathematical symbols etc. in equations.
There are two ways to do this.
The first is using the Alt key along with certain codes as follows:
The codes for these symbols and more can be found HERE. Some of the codes don't give you the symbol you're expecting. Don't ask me why, I think it must be something to do with your keyboard language settings or something.
NOTE: These codes are for Windows PCs. Instructions on how to do this on a Mac are HERE
Another way to do this is to use HTML character codes. These are codes that start with "&#" followed by a code and end with a semi-colon ";" (without quotation marks).
Type these codes where you want the symbol to appear in your post. When you submit the post and your browser renders the page, these codes will be replaced with their corresponding symbol:
Here's a few common ones:
Don't forget to start with "&#" followed by the code and end with a semi-colon ";" (without quotation marks).
A full list of these codes can be found HERE

The first is using the Alt key along with certain codes as follows:
- Make sure Num Lock is enabled on your keyboard
- Hold down the Alt key (the one to the left of the spacebar)
- On the numerical keypad (on the right hand side of your keyboard) type the following codes to place the symbols in your text when posting
- Degrees [°] »» 0176
- Power of 1 [¹] »» 0185
- Squared [²] »» 0178
- Cubed [³] »» 0179
- Quarter [¼] »» 0188
- Half [½] »» 0189
- Three quarters [¾] »» 0190
- Plus/Minus [±] »» 241
- Let go of the Alt key. The symbol should now appear in your text

- Square Root [√] »» 8730
- Divide [÷] »» 247
- Delta [Δ] »» 916
Don't forget to start with "&#" followed by the code and end with a semi-colon ";" (without quotation marks).
