Real-time 2 different ocr and calculation them

Hi, I would like to execute this process.

There are 2 values on my web browser ( on the same tab). These values refresh every 1 sec (in the same location). Let’s say the first value is A and the second one is B. These are floating numbers such that 13.56, 8.01, etc. I would like to extract them and make a calculation like C = A*12.6 / B. I would like to construct and see the C value in every 1 sec. Maybe store the values. How can I achieve this? Is it possible in UI.vision?

As a starting point see:
