**Copy a symbol below and paste into the UPchieve chat window.** On MS Windows you can type in an alt code instead, on Mac OS you can open an on-screen keyboard and press the character. None of these options is particularly speedy, especially when using multiple symbols. Not all characters exist, including apparently a subscript y or t.

------
These are nice, but students also seem to be comfortable seeing x^2 for x², sqrt(x) for √x, writing out theta, etc. The less-than sign (<) is used for angle sign (geometry). 

Mixing cases or just combining letters can sometimes substitute for subscripts: vI instead of vᵢ. This can be a little confusing, often using spaces to better separate the terms is helpful.
