When I can't sleep I make up mental math quizzes - eg: what are the 5 differences between 17 and 8?
Next number in sequence - 1,2,3,6,7 ?

When I'm doing the 15-minute run in gym class, to pass the time, I prime factorise the time displayed on the timer.

I like to take huge numbers and figure out if they're divisible by 7, and I enjoy stuff like this

But that's probably too easy for most of you, I'm only in grade 7 and it's starting to get a bit simple
I'm going to try out these things sometime.

Do you do the official CNML contests? If math is your thing, that's a pretty easy way to gain fame among your peers. You should also do the U of Waterloo Gauss contest. This year's is probably over by now, but if you're not already doing them, you should next year. In later years, it's also possible to win modest sums of money from these contests (I recently won $200 from the grade eleven Hypatia contest). You've got everything to gain and nothing to lose... except maybe a few dollars, if your school is too cheap to sponsor these contests, like mine is.

Well, it depends what CNML stands for I was one of the three kids picked to represent our city at the provincial finals this year, and that link up above was the test they took last year. I'm studying for that.

I,be never entered in one of the waterloo competitions, but I practice the Gauss grade 8 and whatever the grade 9 one is called in my spare time. I really like those kind of word problems!!

Do you live in Ontario?

Canadian National Mathematics League. The grade nine Waterloo one is the Pascal. If you're good at explaining things, also look up the Fryer contest. It's four questions, but you have to show all your work, and you're scored based on the clarity of your answer.

I live in Manitoba. It's quite nice, since I have a much higher chance of being the regional champion. I wouldn't stand a chance in Ontario.

This is so awesome!! Things is, I wouldn't want to explain it, just solve the answer because it takes too long to explain

Anyhoo, here's the link to the one I opened because it was really great:

Shadows, now you've got my brain into trying to factor every number I see. It's really messed up

Third place in Ontario for the Waterloo contest is pretty good, no?

Might try that other one you are talking about.

I find the joke ironic to me because I use a 24-hour clock to begin with and also factorise the time.

One time in a hotel room with 3 friends, me and one friend raced to factorise the time in the wee hours of the morning while the other two yelled at us to shut up and go to sleep
