Well no it turns out I was wrong and I still cannot get to the right answer. Here is the new updated code. The answer is -4391 I need to try and get to that answer. has anyone any ideas?

def add(a, B)/>: print "ADDING %d + %d" % (a, B)/> return a + b def subtract(a, B)/>: print "SUBTRCTING %d - %d" % (a, B)/> return a - b def multiply(a, B)/>: print "MULTIPLYING %d * %d" % (a, B)/> return a * b def divide(a, B)/>: print "DIVIDING %d / %d" % (a, B)/> return a / b print "Lets do some maths with just functions!" age = add(30, 5) height = subtract(78, 4) weight = multiply(90, 2) iq = divide(100, 2) print "age: %d, height: %d, weight %d, IQ %d" % (age, height, weight, iq) #puzzle for the extra credit, type this in anyway print "here is the puzzle." what = add(age, subtract(height, multiply(weight, divide(iq, 2)))) print "That becomes", what , "Can you do it by hand?" # add(age, subtract(height, multiply(weight, 25))) # add(age, subtract(height, multiply(205, 25))) # add(age, subtract(height, 230)) # add(age, subtract(74, 230)) # add(age, 304) # add(age, 304) # add = 339

Your code looks fine. Can't imagine what the issue is.
