Describe the bug The formula was wrong with (90% : 90%) + (90% - 90%) The app's result is = 0,09 But other app, the expected result is = 1,09

To Reproduce Steps to reproduce the behavior:

  1. Go to the application

Expected behavior The expected result is = 1,09

Contributor guide

Research direction
Investigate the percentage calculation logic in the expression parser or evaluator to understand why (90% : 90%) + (90% 90%) returns 0.09 instead of 1.09. The issue likely lies in operator precedence or the handling of percentage as a unary operator.
