Pyqt5 + strong math + Py programming language

Hey , can you help me with this next task
I have a UI app already designed in pyqt5
In the UI you can find a tableWidget, buttons, and textboxes, so you can send information to the tableWidget
the information in the tableWidget would be used in a formula that calculates a result
The formula have math functions and decision taking syntax
if yes do this if no do this....
The formula is already written but in words not in python

Need you to translate that formula to python and make the connections
+ Make some functionality work
