[1]Counter clockwise = ccw, clockwise = cw
[2] Please start each day’s homework on the top of a new page, and label it clearly 1, 2, 3…etc. Remember that the expectation is that you spend a half hour working on problems that you can do. If you are bored, do the harder problems, challenged, the easier.
