You are more than welcome to seek help from me or your classmates, but I highly recommend that you first attempt seriously each problem on your own. Struggling through an exercise is a common thing in mathematics; in fact, this is the way to understand the material in depth and make it your own, rather than just memorizing a bunch of "nonsense" tricks.
Homework will be collected in class every Thursday, unless stated otherwise below. Please note that no late homework will be accepted.
