Hiya there! Lets get this straight that the value on right gets assigned to the variable on left. Period!. Your syntax is all wrong. Other than that , everything seems on point except for you dont have to use Math::E when you're already importing Math module on top. For best practices, Remove the import from your code and use Math::E instead, you're good to go.
