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

    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...)
