Edit on Chapter 15 Convolutional Layer Notes

Hey! Thanks so much for the cs231n notes! I'm studying for the midterm tomorrow and noticed a typo in one of your formulas that confused me for quite a few hours. 
On the first page of Chapter 15 (page 77) the pdf looks like: 
W2=(W1−F + 2P)/(S+1)
but it should say: 
W2=((W1−F + 2P)/S)+1

Thanks!
