That's OK for simple calculations, if you don't need the decimal point.
Without the decimal point you get integer calculations...
Also, if you want to use variables for interim results, you have to switch all the time.


(Sometimes, I'm using scripts for standard calculations where I accept inputs like '1?1' for '1.1' to avoid switching. Maybe I should add the decimal point to the X Terminal keys, but then it still would not be too comfortable to use Python as calculator with interim results.)
