Maths!

[groundcontrol]

Well, there was only a section dedicated to Science! so I wasn't sure where to put this. I'm looking to sharpen my 'numerical reasoning' and other related mathematical skills, would anyone happen to know of a good textbook to work my way through? Thought about that 'Brain Training', but I think that's more dedicated to mental arithmetic rather than working out problems. I know this kind of stuff is available online but to be honest I need something concrete in front of me, where I can't open a new tab to pornhub when I get bored after 5 minutes. Also a lot of the sites look like they were created in the 90s.

Its been 10 years since I did my GCSEs, for which I did very well at, and managed to get a degree in Economics but I have lost my 'edge' somewhat, which I will need to regain for the purposes of testing for potential jobs.

Thanks.

Thanks all. The King of Maths app sounds pretty good and something I can do whilst at work to pass some time, albeit at the mercy of iPhone battery life.

Past papers are a good shout, GCSE level is all that's required really. I find I can solve a lot of mathematical problems quite easily but using my own method based on common sense rather than anything else, so in a timed environment it all goes to shit. Correct method for things up to the level of compound percentages, dividing fractions etc with quick mental arithmetic would put me in good stead.

As above I stopped paying attention when we got to differentiation. Did a couple of maths/stats modules in my first year at uni but after that it got a bit complex and too much effort to keep up to speed with something that doesn't come to me naturally.

Can anyone with kids of GCSE age (or anyone of GCSE age) let me know what textbooks they're using?

Appreciated, PM'd.
