There, now the errors are clear

[idle apex]

try passing x and y to the add function e.g. int add(int x, int y) { return x + y } for the declaration and int z = add(x, y); for the reference.
then declare your variable and assign it the user input you like such as:
int x = getuserinput(); the rest of the errors are similar.

[primal sky]

bc ur not passing the x and y to the add function

u don't have a variable to store that value u pass
