Today's Free App of the Day is Calculator Plus
A well reviewed calculator app. Some reviews say that the order of precedence of operations is not recognized--I haven't had a chance to try that yet. One review indicated it wouldn't work unless connected to the 'Net. Mine worked fine in airplane mode.
334 of 363 reviews are four stars and above.
These apps are compatible with the original Fire and with my Fire HD 8.9" 4G.
