I’m currently working on fixing a bug in my calculator logic, specifically in the equal function. The issue seems to be related to how numbers and operators are being processed and evaluated.

Right now, when I press the equal button, the function doesn’t consistently return the correct result. Sometimes it fails to compute the expression properly, especially when multiple operators are involved or when chaining operations.

I suspect the problem lies in how I’m storing and parsing the input values—both numbers and operators—before passing them to the evaluation logic. There might be a flaw in the way I’m handling operator precedence or in how I’m converting the input into a valid expression.

If anyone has experience debugging calculator logic or managing dynamic input parsing, I’d appreciate any insights or suggestions!

Here’s my snippet of my blocks for equal function

Hello @anthroi, welcome to Thunkable! 🎉

The equal conditions are used because it is not possible to set the arithmetic calculation dynamically. So all the different blocks must be added, and a variable defines which must be executed.
