One common typing error that you should watch out for
is forgetting to end a superscript or subscript
with a blank or other delimiter (like tilde).
For instance, you often see output like
.EQ
f(x sup 2)=1
.EN
because there wasn't a space left between the 2 and the ).
What we really wanted, of course, was
.EQ
f(x sup 2 )=1
.EN

Modify "Example" to produce this output, then type "ready".
