what = add(age,multiple(iq, substract(weight, divide(height,4))))

Раньше это бы напугало меня, но я решил задачку вручную с помощью интерпритатора python. В конце главы автор предлагает нам сделать некуюформулу "Try 24 + 34 / 100 - 1023 as a start. Convert that to use the functions. Now come up with your own similar math equation and use variables so it's more like a formula." Я долго ломал голову но единственное что смог написать это пошаговое решение, вот код
 

first_step = divide(height,4)
two_step = substract(weight, first_step)
three_step = multiple(iq, two_step)
four_step = add(age, three_step)

Как бы вы решили данную задачу для получения формулы решения?

вот весь исходник

def add(a, b):
	print "ADDING %d + %d" % (a, b)
	return a + b

def substract(a, b):
	print "ADDING %d - %d" % (a, b)
	return a - b

def multiple(a, b):
	print "ADDING %d * %d" % (a, b)
	return a * b

def divide(a, b): 
	print "ADDING %d / %d" % (a, b)
	return a / b

print "Let's do some math with just functions!"

age = add(20, 6)
height = substract(200, 20)
weight = multiple(40, 2)
iq = divide(190, 2)

print "age: %d, height: %d, weight: %d, iq: %d" % (age, height, weight, iq)
what = add(age,multiple(iq, substract(weight, divide(height,4))))

first_step = divide(height,4)
two_step = substract(weight, first_step)
tree_step = multiple(iq, two_step)
four_step = add(age, tree_step)

print four_step
print "That becomes:", what, "Can you do it by hand?"

Надеюсь это не слишком сильно напрягает.

Помогите понять что не так?
