I used to hate maths as school but as I've grown older and used it to work out problems in the markets I've also used it to solve all sorts of problems.

There is a beauty to it I never saw at school. I reckon they should use real world examples to explain some of the beauty in maths.

Of course you can get by without it, but you get some really elegant, sometimes counter intuitive solutions when you understand key concepts.

Here are a couple for starters: -

I use simple maths when trading, does anyone use complex stuff like equations etc? There must be a maths genius in trading.

Iv spent a bit of time on maths in early stages of learning to trade soccer, however I learnt that my ratings would never be better than the market. In my opinion it's best to realise that the market is relatively efficient and work around it by stealing a few ticks.

There are loads of wonderful equations you can use when trading.

Not maths related but if you can't find your car in a car park, stick the keys in your ear.

I love maths and was in the top 1% of maths students at university.

I took a different career path. So my maths skills sat largely wasted although I would be occasionally sought out at my workplace to explain something. It was generally so ridiculously easy that I couldn't fathom how so many people know so little basic maths.

I came to betfair and bet angel for relaxation because of my love of maths. Even now I don't use anything remotely near the complexity of what I studied at university. Rather it's all secondary school algebra.

I watched the Imitation Game last night and felt a small pang of wasting my skills. I am certainly not a mathematical genius in the class of those people, rather I was very very good. What struck a chord with me was I love solving problems.

The only thing i really use in terms of maths is percentages, a risk reward type of trading.

Also not maths related, but appeals to the nerd in me.

Years ago I heard about a teacher from MIT who found some street kids in Brazil who used complex, counting systems to sell candy without any schooling. They had developed it themselves. Just shows how we use maths everyday without realising it.

Here's an article I just found on it, a bit chunky but worth the look.

I also hated maths at school but now see it as the greatest art form ever discovered.
I'm becoming one of these :geek: ....

If mathematicians were so good at predicting a game, there would be no reason to play the game.

One thing that I find interesting is that most trading opportunities don't appear significant by a statistical point of view, but stand out like dogs balls on the ladder.

Rather than predicting the result, mathematics may be useful in showing when the odds are in your favour. I would back any horse in a race provided I could obtain the odds I wanted
