Did I get the indentation wrong?

I’m having issues too, only I went with this. Not running though. Could sure use some help.

Defining a function only gives it a name, specifies the parameters that are to be included in the function and structures the blocks of code.

Once the basic structure of a function is finalized, you can execute it by calling the function

you never call the functions, thus the functions never execute

@balint2, you call the functions, but the function calls are nested inside the functions. The function calls should be outside/after the function

Hi, I still don’t understand why “mult_x_add_y(5,2,3)” doesn’t work…

Edit: Never mind, I worked it out. I wasn’t paying attention to indentation…
