So, I'm in collage now and trying the Microsoft Math trial thingy and damn I'm loving it!
Anyways, I'm not very experienced at the thing so I'm having some issues, but the most important one and the one I hoped you guys could answer is types or comments ...

What I want is to be able to define my values as a type, (kg, km, light years, ect.) is this possible or is there away around so that I can atleast look up what type it is?
Thanks in advance
