|Model:||DUAL LEAF SL-200|
This "DUAL LEAF" 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.
The calculator thinks √-9 = -3 which is very uncommon for calculators newer than the early 1970's.
Thank you, Paul Coenen, for donating this calculator.
