I agree best non-programmable calc ever...would be perfect except for the auto power off and it's power off loss of memory. They upgraded the case and buttons now in the 2nd version...looks better too.
I'm pretty sure the "two-way power" refers to the fact that the calculator is primarily powered by a battery cell, as well as by the solar panel in the top right corner that you are mentioning. The benefit of this is that if the battery dies, the calculator will remain usable due to power coming in from the solar panel.
i followed until 17:26, the calculator only gives x1 and x2 value. There are no x/y value minimum after i press the down arrow..May i know, what's the cause of it?
Oh hell yeah finally a review for the Casio fx 991 es plus C I searched so hard for this thanks firetto very epic
