Hope you are new to LabVIEW, It better not to use sequence structure unnecessarily, go through the basics of labVIEW and Design Patterns (Probably simple state Machine Architecture)

Hi Lapig,

Welcome to the forums and LV. Your code has a polling style architecture with sequence structures, the reason we recommend going for a state machine over sequence structures is so it can be responsive, reconfigurable, adaptable and scalable. It is a lot harder to do this with stacked sequences.

As a calculator has a lot of user interactions I'd also recommend using a event structure. You could start revising your code by looking into event structures and making a simple VI with a single while loop and single event structure.
