Highs and lows
The calculator app offers a lot of stuff, a lot of digits in the result, but has for me a key weakness if not even a bug: 1 + 2 = * 3 results in 7, but this is wrong, since it fails to understand that the = terminates the addition yielding a 3, which has to serve as multiplier for the following multiplication.
