Maths definition difference between countries

[user789653241]

I am currently learning maths myself from free online course.(Khan)
When I read some post about maths in some thread, the way they call it differs from between the country.
Currently I am working on [[https://www.khanacademy.org/math/math3

Mathematics III]] on Khan, which I believe it was high school level(16+) in my own country.
What are levels compared to English maths program? When do they learn these in England? And what are they called?

after a brief look at the syllabus, it reminds me of 'O' level maths, but that that was 40 years ago! Not sure about nowadays.

Thank you Ifailed. But have no clue about o levels!

It does look as though it is roughly comparable with A level. Some things like radians dd did in AS, but things like complex numbers are only introduced in Further maths A level. I have only looked at it briefly, so cannot say if it covers all that is included in A levels.
Currently A level consists of four compulsory core units and a choice of two applied units from mechanics, statistics or decision maths. So six units. Three units are taken to get an AS and three for A level. However, this is about to change into exams taken only after the second year.
I have not looked at Khan Academy for some time and it seems to have changed a bit. There are still the wonderfully easy to follow videos though, so I too will probably give Mathematics IIII a go as well. Thanks for pointing it out.
Do you think the site has got easier to find your way around as that is what I was finding difficult with it?

but things like complex numbers are only introduced in Further maths A level.
Things have certainly changed then. I recall doing i2 = −1 at O level.

Thank you both.

I am only doing this since I found a pleasure in learning maths again as an adult, since I didn't even try it hard enough when I was in school.
Yes, Khan has changed, and constantly changing. I do find Sal's lectures very easy to follow.

I think the site has improved massively. They have introduced diagnostic tests in each section and suggests what to work on, or simply just move on to next.
Subject choice is still vast and complicated, but seems a lot easier to find your way around than before.
Massive improvements to parent/coach function as well, now you can assign videos, practice or written article etc. with just with choosing "assign" button on the top of your screen. The other day, I was reading about article on total eclipse and pressed the button, article appears on home screen on my ds's account instantly. Very handy.

I will look at the site again then. I too have got interested in maths again, having helped my dd. I think if the internet had been around when I first did maths, I would have done better. As hobbies go, I can't help thinking it is a bit odd, but a Sal Khan tutorial seems as good a way of whiling away a half hour as any TV programme. I do worry it may lead to harder internet use, such as MIT MOOCS.

I am now doing maths all the time if I have spare time, and dh thinks I'm very weird.
I even checked out calculator Sal uses on tutorials, but had to give up getting it because it was £539.18 !!!

Happy mathsing!
