Clarification on HW6-Q8

[TonySuarez]

In Q8 it is asked the "...closest to the total number of operations required in a single iteration of backpropagation (using SGD on one data point)".

My question is if we have to account only the backpropagation step or, instead, one complete iteration of the backpropagation algorithm, which includes the forward propagation, the backpropagation and the SGD updating steps.

Thanks in advance.
