a) On the number line, $\\var{a1}$ lies to the right of $\\var{a2}$ so $\\var{a1}>\\var{a2}$.

b) This is the reverse of a) so $\\var{a2}<\\var{a1}$.

c) $\\var{c2}$ is to the left of $\\var{c1}$ so $\\var{c1}<\\var{c2}$.

d) $\\var{d}$ is equal to $\\var{d}$, hence $\\var{d}=\\var{d}$.

e) Clearly, $\\var{e1}$ is less than $0$, so $\\var{e1}<0$.
