Very good value for money, this calculator is very good for school, and packs a lot of power with more functions than any other Scientific unit in this price range.

Top of the line scientific calculator, capable of working with complex numbers, matrices and pretty much anything else. I recommend this calculator for anyone involved in scientific or engineering studies.

Carel, South Africa. 2 November 2016

I wish I had this calculator when I started Standard 6 in 1998 already!
Truly one of the best things I've bought in years, which should last me the rest of my life.
This calculator has given me the confidence I should have had when I was still at school!
The question is not what can the FX991 do, but rather, what can't it do!
