Calculadora con memoria

Simple calculator with history for all operations done. This calculator can be compared to a classic financial calculator with ticker tape onto which all operations are written.

Classic memory buttons are available:
MS = Memory Store
MC = Memory Clear
MR = Memory Recall
M+ = Memory Add

When you ask for operations history and select an old result, this one becomes part of the current operation, acting as a memory recall as well.

Operations can be:
- exported into external file onto phone SD card
- send to an email address
