"Put all the cups of one color in a box..." If there are more than n cups of this colour than you will have still k colours left.

comment Good book for self-studying Binary Relations
The preface does not require an abstract algebra course that focuses mainly on binary relations but the binary relations material contained in the first weeks of an undergraduate abstract algebra course.

comment Help with finding the real zeros of a polynomial
$(x+1),(x-1),(x+2),(x-2),(x+4),(x-4)$ are not the possible zeros of the polynomial, they are possible divisors or linear factors of the polynomial. Th possible zeros are $+1,-1,+2,-2,+4,-4$.

comment How to calculate running time of code?
-1 One way to solve the problem is only mentioned in two sentences. It doesn't answer the question becuase it does not show how to calculate the formulas. I don't think that one can derive a 4th degree polynomial by looking at your patterns

comment Proving a limit with epsilon delta definition
I don't understand what you mean by "f(x)=L+- ε 2=(1/2+-ε)x + 1 x= 3+- 2/ε". can you state in your post using the $\varepsilon$-$\delta$ notation what you have to prove?
