Here's the break up
Forward propogation  22
Backward  3
Update  22
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.
