This is a strange calculator. When you first see it you might
think it's a plain four-function calculator but it is actually a
scientific one, of sorts.
The key placement is really odd. The "="-key is somewhere in the middle of the rightmost column, and the "F"-key (to select the scientific functions) is somewhere in the middle as well.
Really strange for a scientific calculator is the fact that
there's no scientific notation for really small and really large
There's a slider to switch between radians and degrees.
This calculator can use rechargeable batteries, there is a slider in the battery compartment to switch between normal and rechargeable batteries.
