(except in the case of word problems, which are too long).
Do your work in pencil, with mistakes cleanly erased, not crossed or scratched out.
For instance, do not use "#" in your sentence if you mean "pounds" or "numbers".
Do not use the "equals" sign ("=") to mean "indicates", "stands for", "leads to", "is related to", or anything else in a sentence; use actual words.
There's no catch — you won't be charged for it, and we'll never ask for it back!
Mathematics is a language, and as such it has standards of writing which should be observed.
If you work in ink, use "white-out" to correct mistakes. If you run out of room at the end of a problem, continue onto the next page; do not try to squeeze lines together at the bottom of the sheet.
Do not lap over the margins on the left or right; do not wrap writing around the notebook-paper holes.
For your work to be complete, you need to on the axes, and do a T-chart, unless instructed otherwise.
Also, make your table or graph large enough to be clear.
