Casio FX-82 AU Plus II

The best calculator in the world, with an AAA battery that lasted roughly three years (it's life was cut short because it was thrown at a wall after its owner recieved a shitty maths grade).

A calculator that helped me cheat on a maths exam.

Person 2: I used the Casio FX-82 AU Plus II
