I want to write a review about the Casio fx-9750GII calculator that I bought thanks to this site. This calculator can be a great help for mathematicians, and for humanities - so generally a godsend. All basic math functions are at a glance. The interface allows you to make it so that even a very complex example in mathematics is solved instantly. The example may not be disassembled in parts, but written entirely. All actions are displayed in "real time". In general, I really liked it.
