Hi @rude1609 ,

The arithmetic_arranger function is not returning anything.

This line print(arithmetic_arranger([“32 + 698”, “3801 - 2”, “45 + 43”, “123 + 49”])) in the main module is not getting a return value.

Instead of the print statements in your function, you can try to append a string variable and return that.
