This assignment is due in class on Monday February 24. Here and everywhere, neatness counts!! You may be brilliant and you may mean just the right things, but if the your readers will be having hard time deciphering your work they will give up and assume it is wrong.

This assignment was written on the HW session of Friday February 7. See BBS/AKT14-140207-181713.jpg.
