Just so you know... using AI generated solutions to complete kata is a good way to get banned.

EDIT: srry for wasting your time i got it forgot to use arrray

This also isn't an issue with the kata. Your function doesn't return anything, so you are returning None, you should be returning a list of strings. (printing and returning are not the same thing)

Why ( -9.21+ -8.97* -0.00+6.51+(5.50+6.81)) equals to 7.26... ?

You can just try to solve it manually:

1. -8.97 * -0.00 = 0
2. -9.21 + 6.51 = -2.7
3. 5.50 + 6.81 = 12.31
4. -2.7 + 12.31 = 9.61

EDIT: nevermind i found another solution

"Idk why my code doesn't work" is not a kata issue.

Idk why my code doesn't work, tests are buggy

Fixed

We should swap actual and expected? Or also include a size check?

this was all i had to do?
omg
i really should've just read the manual

Or maybe not.

One could argue that order of evaluation of an expression is precisely defined (operator precedence and associativity are all specified), so a conformant solution should not produce results different than reference solution if it applies operations in the correct order.
