did not understood

where am i wrong

int addTwo (float 1, float 2) { return 1 + 2; }

I'm pretty sure variable/param names can't start with a number. And in the return statement you are returning 1+2, which will always return 3.

Make it

int addTwo (float first, float second) { return first + second; }

I'm not sure if that's the exact syntax, because I have not worked with obj C, but u get the idea.

And why are your params 'float', when the function is 'int'?

You're correct, and it also should return a float, so: (your syntax was fine):

float addTwo (float first, float second) { 
    return first + second; 

Yep. Either make the params int, or the function float.
