Strange, this calculator is almost identical to the Casio DUAL LEAF
SL-200 but not entirely. The solar cell is different and
what's more this calculator does not have the negative square
roots bug the Casio
DUAL LEAF SL-200 has.
Also strange is the fact that this calculator mentions DUAL POWER but I haven't been able to find a battery anywhere. If it has one it's well hidden. Other than that, this calculator folds up to a small package that easily fits any pocket. This has the advantage of getting bigger keys and a better display into a small calculator. This calculator has basic functions, a change-sign key, percentages and square roots. |
