Function returns unaccurate value

[raulfloresgp]

This is an example of an issue that I have:

why if a function calls another function the return of the called function is not accurate:

I have inserted some print instructions to evidence the outputs. thank you for your help.

def multiplicacion(a,b):
    producto = a*b
    print producto
    if a>b:
        return producto
    if b>a:
        a += 1
        multiplicacion(a,b)
    print str(producto) + "END"
    return producto


def maths(a, b):
    pluss = multiplicacion(a,b)
    print str(pluss) + " end "
