Valid Objective-C method is invalid in Objective-C++?

I've just changed an ObjC file to ObjC++ by changing the extension from .m to .mm. Now, one of my methods gives the error: Expected expression

The following code is an example that works fine in ObjC but NOT in ObjC++:

- (float)sum:(float)a and:(float)b
{
    return a+b;
}

- (void)run
{
    float s = [self sum:1.5f and:2.5f]; // ERROR HERE
    NSLog(@"Sum = %.1f", s);
}

The only thing I've changed is the file extension. Any idea what's going on and how to fix it? Thanks!
