Performing a particular mathematical operation caused the app to initially freeze and then crash

[kodeblacc]

Expected behavior

The calculator should be able to perform calculating operations within it's limit without any hassle.

Actual behavior

When I tried to perform the operation 10^3 three times, the calculator initially froze and then eventually crashed when I tried pressing other inputs to abort the operation.

How to reproduce

• launch the calculator
• turn on fraction mode which is indicated by A/B on the top right of the calculator
• try to perform the operation 10^3 three times and the app freezes on the third time.

PS: For single unit number eg 1-9, the app freezes the fourth time. Also this is only reproducible when the fraction mode is switched on.

Maybe some time restricted operations like TimeConstrained used in the Symja console may help?

In this example the calculation is restricted to run max. 10 seconds:

>> TimeConstrained(1^3^3^3^3, 10)
$Aborted

1^3^3^3^3 is parsed as Power(1, Power(3,Power(3,Power(3,3)))) so the intermediate result of 3^3^3^3 gets to big.
