Type or write (neatly) your assignment on notebook-sized
paper. If you handwrite your assignments, use a pen, since I find
pencilled writing hard to read.
Make sure that I can understand what the problem is without
having to look it up.
Be sure to leave plenty of space for comments. Usually you
should leave a third of a page per proof, plus nice-sized margins.
Be sure to staple the pages together. You should own
a stapler by now, but if you forget, there is a stapler in the third
floor computer lab.
Make sure that you cut off the squigglies on paper ripped out of
a spiral notembook.
For problems that don't involve proofs, you should show enough
work so that any student in the class can follow your solution.
Just writing the answer is never enough.
Proofs should be written in complete English sentences.
Proofread what you have written to make sure it makes sense.
Don't try to fake a proof. Instead, acknowledge the gap in
your proof. Better yet, come talk with me beforehand and see if I
can help you close the gap.
