About this product

The FX-991EX is the calculator most students are told to buy. It covers statistics, matrices, complex numbers, integration and a basic spreadsheet, with a sharp 192 × 63 display that shows equations clearly. Solar and battery power mean it rarely runs out.

It is approved for many exams but not all; check your board's list. The keypad is dense, and the menu system takes practice compared with simpler models.
