I can answer all questions up to, and including, graduate level mathematics. I am more likely to prefer questions beyond the level of calculus. I can answer any questions, from basic elementary number theory like how to prove the first three digits of powers of 2 repeat (they do, with period 100, starting at 8), all the way to advanced mathematics like proving Egorov's theorem or finding phase transitions in random networks. I do not understand why Number Theory is not included in "Advanced Mathematics."


Most questions on number theory, divisibility, primes, Euclidean algorithm, Fermat`s theorem, Wilson`s theorem, factorisation, euclidean algorithm, diophantine equations, Chinese remainder theorem, group theory, congruences, continued fractions.

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.

Hello Kenneth  The amount of work done, w, is proportional to the number of men, m,  the hours per day, h, and the number of days.  So w = kmhd  substituting gives w = k*24*8*15 = 2880k  Now the same w

I think I have been over this with you before.  The number of houses is jointly proportional to the number of men and the number of days.  So h = kmd.  Substituting the given gets you to k = 1/40.  So

I'm not sure if I understand the question, but I think you mean 24 hour clock time.  All times from noon to 1 minute to midnight have 12 hours added, so that confusion between 10 am and 10 pm does not
