hi, i'd like to enter this competition (i'm 14), but it seems too much like a game rather than a serious competition.. the real joy in mathematics is not fast calculation, but rather the arts of numbers and shapes. I'm currently studying projective geometry and modular arithmetic (in Diophantine equations, to be precise) ; and i notice that fast calculation is most nearly pointless the further you advance into mathematics. In pure mathematics, it's great to be able to do fast calculations. In applied mathematics (simple or difficult), you will almost never do unassisted work (without a calculator or programs).
By the way, bobbym, I think this is a great site for all kinds of maths! However i was looking for a section where maybe i could learn totally new things, rather than just reading others' posts on their confusion (even though it's fun to help others out! ) Do you think you could maybe add a section dedicated to materials for learning and advancing in mathematics, such as articles or short explanations on advanced (college) non-calculus mathematics? It's just a thought; I'd greatly appreciate it!
