Going off to japan soon in about 2 weeks. meanwhile, having lots of band practises to get ready for concert in japan *gasp*. this inevitably leads to stress, and what a better way for me/you to destress than me giving you puzzles and you solving them?

so, here goes...

1. Show n^3 - n is divisible by 3 for all natural n. (this one's a doozy. i can't type powers properly on blogger, forgive me.)


2.If x , y∈Z+ , find the value of x , y if x^2 − 4y^2 = 37. Do not use guess and check. (this one's another doozy. the Z+ thing is supposed to be the symbol "Z" used in set theory. except that i can't type it here.)

you maths club people should have no puroburum at all. *wink*.

have fun! will reveal answers later.

Till next post...
