 Apr16 comment combinations help, 18 boxes, 42 marbles, each box can hold 6 marbles. how many combinations? One final question, should we count arrangements in which some boxes end up being empty? Apr16 comment How to Prove with Mathematical Induction $3^n > n^2$ Thank you JMoravitz, I was considering adding a section on how to prove that statement. Apr15 comment combinations help, 18 boxes, 42 marbles, each box can hold 6 marbles. how many combinations? So the boxes and marbles are all different?

The subindex tells you in which graph this degree is being taken. So $\delta_G(v)$ is the degree of $v$ in the graph $G$.

Apr14 comment Book recommendation for Abstract Algebra You're Welcome, if you want to learn with categories Aluffi uses them a lot more than Rotman. Apr14 comment Albert, Bernard and Cheryl popular question (Please comment on my theory) Oh ok, I didn't know it was a convention.

This should be explained clearly. Apr14 comment Albert, Bernard and Cheryl popular question (Please comment on my theory) Thanks for the answer, I think that this is the official solution, although I really feel like they should explain how it is that Bernard knows.
