Must have for engineers and mathematicians
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!
