# Is the Casio FX-991EX allowed in Edexcel A-Level Math exams!? watch

1. I'm confused because it says in the syllabus that calculators with 'symbolic' integration are not allowed, yet nearly everyone uses a Casio FX-991ES which clearly has an integration function! So whats the deal? I know graphing calculators are not allowed but is the Casio FX-991EX allowed?

Most invigilators don't have a clue, so you will get away with it (If it happens to not be allowed). But look at your specific exam board for details.

Graphing calcultors are allowed, as is the fx991. The integration button is purely numerical (i.e. it can only do definite integrals) which isn't the same as symbolic integration

so symbolic integration is just integration where it pops out the whole expression with a + c at the end, not just the definite number?

Yeah so it would tell you the integral of x is x^2/2 +c. Graphing calculators are allowed but if you get one be careful as quite a lot do have the capability to do symbolic integration which is why a decent number are banned from exams
7. Crap, I feel dumb. Thank You xD so the calculator is allowed then

I'm getting this calc https://edu.casio.com/products/cwiz/fx991ex/ ,its not a graphing clac so i should be safe and I'm pretty sure it's allowed then because It does regular numerical integration like any other normal scientific calc.
9. I've used the Casio FX-991ES on every single edexcel exam that i sat and no one said a thing. In fact everyone in my class used it. And as someone pointed out, most invigilators don't have a clue, one of my friend brought a graphing calculator and when the invigilator spotted it, he just asked if it was allowed and my friend told yes, and that nothing happened :P

anyone tell me how they'll give you an advantage like I'm doin c3 n c4 again & I didn't use one last time, did I miss out or? I can see it making it easier because it draws the equation for you but other than that

11. Yes, it's allowed. It doesn't have symbolic integration. I've used it without problem for GCSE and AS levels.

Allow you to check answers, but if you can't get that far, they are useless.
