Math is irrelevant. You will be assimilated. Resistance is futile.
math questions help me!!!!!!!

why do u say u have no competition among gifted middle schoolers and high schoolers if you were telling me going rudely like "go to your aopsers they know better than me"? i just dont get it. it doesnt make sense.

stop repeating that and just get ur @$$ out of ur ****ing nonsense!!!!!!!! U DON'T COME HERE TO SPAM, BUT TO HELP ME WITH THE MATH!!!!!!!!!!!!!

You know you love me, don't deny your feelings. You want me to stay and repeat "Math is irrelevant. You will be assimilated. Resistance is futile." I know it.

I do because you seem to think they know everything, I think what you're asking is strictly middle school and they should know how to help you.
once read my number theory book about remainders. what's the fast way of finding the smallest number with a remainder of 9 when divided by 10, R8 when div. by 9, R7 when div. by 8, and so on?
AND another one:
Three players each have a red card, blue card and green card. The players will play a game that consists of three rounds. In each of the three rounds each player randomly turns over one of his/her cards without replacement. What is the probability that, at the end of the game, one card of each color was turned over in each of the three rounds? Express your answer as a common fraction.
