Hi, "Write a function that takes in two numbers and recursively multiplies them together.".. What does it mean ?
if a = 3 and b = 2, does it mean : 3x2+2x1+1x0 ? or 3!x2! ?
Thank you

maybe you are supposed to white a function that reproduces the * .means that u cant use multiply but + 
 so if u want to multiply 2*3 ull have to do 2+2+2....maybe.... but not sure really

Hi, thanks to stop by. ;)
This comes from : 6.189 IAP 2011: Optional Recursion Exercises but they don't seem to say anything about operator use ?..

hmm never done or seen that course...so cant really help u...its just in many courses they show u or ask you to make that kind of an exercise , that's why i mentioned it
best of luck with it

What I think s meant is that if you have a multiplication like 4 * 2, you multiply it as follows:
4 * 2 = 2 + 3 * 2
3 * 2 = 2 + 2 * 2
2 * 2 = 2 + 1 * 2
1 * 2 = 2
This can be programmed with a recursive function. (Of course it'd be better to decrement the two instead of the four...)
