The calc function basically executes the third function with the other two parameters, so calc(-1, 9, sub) will be the same as su (-1, 9). The sub function returns y - x, which is 9 - (-1), which is the same as 9 + 1. 9 + 1 is 10

The third Function calc is just taking 2 args and 1 func to call that func again with the same arg being reversed,you gave -1 and 9 and the func calc revoked sub and made it 9 - (- 1) and so it returned 10. Hope that helps ;)
