Hi, after renaming the function to `mult_x_add_y`

And now, add `x`

and `y`

as parameters of the function, after `number`

.

Maybe, it would help to precise that the function has 3 ( THREE ) parameters : 1 - number, 2 - x and 3 - y

this kind of precision would help understand the change in the numbers of the parameters, and ease the execution of the following instructions.
