Simple Bubble.io Workflow for Calculations

I need a straightforward Bubble.io implementation to conduct basic arithmetic operations. The workflow should be capable of performing:
- Addition, subtraction, multiplication and division.

The results of these calculations should be:
- Displayed immediately
- Stored for future use.

Ideal candidates for this project would be proficient in Bubble.io and have a solid understanding of basic mathematical operations. Experience with creating workflows on Bubble.io is essential, and the ability to ensure that results are both instantly visible and saved for subsequent reference will be key to the project's success. This will be implementing the workflow on the existing site, please send your best quote. I have tried to run the calculation myself but I am struggling to make it work due to lack of knowledge of the platform.
