Succinct. Thanks!

Thanks David, glad you found it useful.

Why does the calculator perform 5x slower after a year? Any fix? Can't install nover/ndless to overclock since it's not supported for the current OS version. Will replacing the battery make it return to its original speed?

[@janmamu8721]

can’t you also use store (ctrl var)
as in x^2 store f(x)

[@danielhribar4487]

great. but how do I perform regular things? like 10/2 = 5?

[@markodonohuemaths]

You go to the calculator application and then do the operation like a regular scientific calculator.

[@danielhribar4487]

When I do that. I get 10/2 (not 5)@@markodonohuemaths

[@siddi47]

@@danielhribar4487 hit control and then "+" after it gives you that answer of 10/2, then it will give you in decimal or whole number form depending on the answer.
