Just wanted to confirm that the answer to the question is 47.
Here's the break up-
Forward propogation - 22
Backward - 3
Update - 22

I hope I'm right.

I hope I'm right.

I got forward = 22 (18 for L=1 + 4 for L=2).

But I am getting different answers for the other two.

Update has to be equal to the total number of weights (correct?). Going from L=0 to 1, there are 24 weights (6 input times 4 output). From L=1 to 2, there are 4 weights (4 input times one output). Total Update = 28

Backward, I get 22, similar to forward. Can you please explain how it is 3? I am probably missing something here.
