Write all your answers on separate paper to turn in, and show all your work where necessary. No credit for answers without work, unless the problem can be done in a single step. Write neatly and circle or box your final answers. Credit will not be given for answers that James cannot read easily. When problems take work, write the steps going down the page, not across or all over the page, so we can easily follow your reasoning. Please staple your assignment together.
