I have a calculator that is correct 80% of the time. But don't worry, every time I use it, I check the results myself.
@MartinEscardo Can you somehow make the calculator physically bigger? Bigger isn't better but it is inevitable and innovation.

@fbulow @MartinEscardo

If the calculator is only correct 80% of the time, one could use two calculators, so that the correct result appears at least on one of the displays ~96% of the time.

As a side effect it would double the size.
