How far has mathematics progressed in the world of Eizon?

I have no idea. But I'm willing to find out.

On a side-note, Zhem uses base-six, my favourite, and IMHO, the best base there is. Screw decimal, screw duodecimal, screw octal, hexadecimal and binary, hexal is the way to go.

If only because you can count up to 35 with your hands (that's 55 in hexal ), and 1 / 3 = 0.2
