This is Discrete Mathematics! Everything is Proof base. PLEASE WRITE NEATLY :) AND no need for long paragraphs on explaining the answer. It's understood. Define sets A and B as follows:A = {n € Z ]n = 6r + 4 for some integer r} andB = {m € Z [m = 18s-2 for some integer s}a. Prove that B ≤ A?b. Disprove that A ≤ B.c. Is A = B?

I need help with this problem and an explanation for the solution described below (Discrete mathematics):
Write the following statement as a mathematical statement. Use variable names to denote arbitrary numbers in the domain. Your statements and should be expressed using algebra. "There is no largest integer."
Circle your answer to each of the following.
John Wallis and other 17th century mathematicians were struggling with how to fit negative numbers into arithmetic without introducing inconsistencies. Explain the reasoning leading to Wallis's paradoxical claim that, if negative numbers are less than zero, they must be greater than infinity. Wallis's argument depends, in part, on the assertion that (3/-1) = -3. Must this be true? Why or why not? If a student proposed Wallis's argument, how would you respond?
This is Discreet math please answer questions with proper formatting for proofs
Please use justification for each step.
4. The statement (3 x 8) x 4 = 3 x (8 x 4) illustrates what theorem or axiom or property in Algebra?
I needed help with part d. (d) between 160 and 161, inclusive are on time But it was nice to double check my answers, but there was no answer for part d Could someone please assist
Thank you so much, could you perhaps elaborate the proofs a bit more, I understand it but somehow it doesnt make sense for me, if perhaps you could use the definitions to elaborate more i would be grateful.
