One giant leap for calculator users
This looks similar to the fx-991ES which I have used for a while but is so much better. The pixel size is smaller, so the screen is easier to read. The algebra functions look more like algebra. And it is so much faster. Trying an integration such as ((x^2-1)/(x^3+1))^0.5 from 0 to 1 on both machines together, shows the difference in speed. It solves polynomial equations up to quartics. I still have to find put what else it will do.

Don't bother
It's rubbish
