You are allowed and encouraged to work on the homework with groups of your classmates. The purpose of the homework is to practice with the material and to improve your understanding. We encourage you to learn from each other, and also to ask us when you have questions. However, the homework solutions that you hand over for grading must be written individually. Be sure that you understand the reasoning for each problem, even if you initially solved the problem with help from your classmates.
