How do you write x-5=0 in standard form?
ebbonxah
Explanation:
In general the standard form for a linear equation is
Ax+By=C
with $A,B,C\in \mathbb{Z}$ and $A\ge 0$
In this case A=1, B=0, and C=5
So we could claim that the standard form was;
1*x+0*y=5
but this seems a bit pedantic.

Let $u \in R$ be a unit of $R$.
