Course 2 :week 1

[khirman]

I didn’t understand the point why dividing a3 by keep prob and later on z3 by keep prob? If we want to scale up . shouldn’t we multiply instead?

Hi, @khirman.

Here’s the reason for dividing by keep_prob.

About the scale up terminology, remember that keep_prob is a number between 0 and 1.

Good luck with week one
