I was taught it is even because it is divsable by 2.

2 x 0=0

The best explanation i ever got as to why 2 instead of 1 (my teacher was useless and infuriating, a future mathematician boyfriend was more helpful) is pure convention. Parity is determined by groups of 2. Otherwise, it would be significant that any number divided by 0 is also 0.

It's just about pairs.

But it seems being divisible by 2 is all that is required.

Yeah. That's pretty much as it was summed up to me. My head exploded until i was told it was mere convention.

But i;ve more a philosopher's mind than a mathematicians. Zero means something else when viewed through that prism.

My former boyfriend tried in vain to coax me into seeing the creativity and logic ... i kept tripping over all of the damn rules, which to my mind are often a thin veneer to claim there is logic.

Oh well, it's been a long long time since I was at school. I loved algebra. If there is a god and he has a language, it'd be maths.

I really don't like maths but i'm good at the basics. I can do simple sums very quickly in my head but f*ck algebra. F*ck it hard.

Had a bit of an eye for geometry but only up to the level i did. I dropped maths as soon as i possibly could.

When we had an exam for our trade maths at Carlisle Tafe I was the only one to get 100% and the only one that didn't use a calculator, which was allowed. I was accused of cheating, I have no idea how I could have cheated though. Still got the 100% on the cert though so they must have realised there really wasn't any way to cheat unless I had the exam papers before the exam and was allowed to bring in a book the answers could have been written in. Still it sucks getting accused.

Yeah i've been accused of cheating before. I didn't do year 10 but was accepted into year 11 providing i sat the end of year exams for year 10. I don;t think they expected me to pass, just wanted me to evidence that i could apply myself. I topped the class in 3 subjects (maths was not one) , primarily because i had recently crammed and i'm really good at tests.

I was accused of cheating then. Had to sit another exam for history. Aced it so they had to accept it.

Ha - ha - first chemistry test at tertiary level I got 100% ...... no study - just knew it all... I regularly ace (100%) many various quizzes... still waiting on Hot Seat ..... been on the list for every quiz show on TV.. never got the invite... must mean something - they're scared.

I hate pretentious maths - no need for it... what I have a need for I am tops at. What use do I have in the real world for that kind of thing? To be a maths teacher? I can work most such things out using my brains... so unless I want to spend my days as a bored out of the skull teacher of irrelevancies .... Cool

2/0 = infinity..... you surely know that...
