i think you will find that it does.

What constitutes useful mathematics? (stupid question, pls ignore)

Please provide significant detail whereby A Level Maths is useless (this is a generalised term, so you'll need to supply evidence that it's completely worthless in all aspects) and your suggested forms of Mathematics are useful.

Edited by:"fishmaster" 1st Nov 2015Good grief, where do I start? oO

Taken out of context obviously

it does, for radians and numerical integration

Well I certainly got A-Level maths without one, but that's probably because the calculator hadn't been invented back then!

All stores I would have thought. My local had a label for the FX-85 (£10) but the FX-83 scans through at £3.

On MEI, Core 1 is a non-calculator module but you may use a calculator for any other module (so the other 5 for A Level maths or the other 11 if you are doing further maths as well).

if you're buying for A-Level maths, the FX-991ES can be found for about £15-£20, and is capable of checking answers - in some sense.

e.g. you have a question that's

a) find the differential of blahblahblah

and you give your answer as a load of Xs - no allowed calculator can do this for you

b) find the gradient when ...

and you have to find a specific number, using your answer to part a

The FX-991ES (and others I guess) can do part b generally using just what was given in the question to begin with. I cannot emphasise how useful this is. If your answer to b is the same as what the calculator says, you can assume you got the whole question right. Likewise, if you get a different answer, you can spend the extra time at the end of the paper going back over that question.

I remember having to pay £20 for the most basic scientific Casio ever - this would have been incredible!

Scanned through as £5 in Penrith
