 Jan1 awarded Necromancer Dec11 awarded Quorum Dec10 comment Using 4 '8's, get the number 24 8 + 8 + 8 and then I don't even need the fourth one, thus my solution is presumably 75% more efficient than the intended one!

Sep25 comment Is there possibly a largest prime number? I think this a great question. The answer is on Google and Wikipedia and elsewhere, but the explanations you found out there are probably hard to understand. There are some people here who could answer this in really nice, plain, understandable language. +1 for sure. Sep9 comment Your favourite maths puzzles Hm, I thought you could. Is there a math.stackexchange question on this? Sep8 comment Your favourite maths puzzles If you have unlimited time and cash, then just keep playing until you're ahead. It'll happen eventually. I must be misunderstanding. Aug28 awarded Scholar Aug28 accepted How can I understand and prove the “sum and difference formulas” in trigonometry? (cos(a ± b) = …, etc.)? Aug27 comment What is $\sqrt{i}$? +1 for introducing me to the term "Argand diagrams" which I'd never heard before. I always just heard "representations in the complex plane" or something. Aug25 comment How to convert a hexadecimal number to an octal number? Does this really fall under "number theory"? I thought number theory was all about the values of numbers, not the notation. Maybe I'm being nitpicky, or maybe I'm just totally wrong. Aug22 awarded Commentator Aug22 comment Pendulum with moving pivot Possibly better suited to stackoverflow. Physics/math questions are okay there, as long as they're programming-related, which this certainly is.
