Scientific calculator for a reasonable price

I bought this calculator as a replacement for my old FX-85WA.
Particularly noteworthy is the so-called Natural VPAM which reproduces mathematical expressions in natural display. Thus, fractions, roots etc. are reproduced exactly as they are known from textbooks. This helps ehrheblich in clarity and is easy to use even for mixed fractions.

The only difference from the FX-85DE plus is that the FX-82DE is operated plus a R03-AAA battery and has no solar cell. This was one of the reasons for purchase, as it requires no special button batteries, but can use conventional AAA batteries, which are mostly already in the household for me. However, to be resolved at the back and therefore the calculator to be completely disassembled to replace six small screws. This is true for the other calculators FX also series so, however, this holding of the solar cell due to many times longer. Practically a small flap to replace the battery would have been, as you know from remotes.

Otherwise all important mathematical functions are available and are easy to use in normal use. In a pinch, also helps a little look into the well explained instructions. So all in all, a rock-solid scientific calculator. However, for the debacle with the very cumbersome battery to be replaced, there is a star deduction.
