RE: Casio fx-570EX vs 991EX
Other than the countries they are sold in, the only difference I can see is that the fx-991EX is powered by solar cells and one LR44 battery while the fx-570EX is powered only by a single AAA battery (no solar cells). This also changes the dimensions slightly. See the specifications on page 42 of the manual.
