Who has two thumbs and loves some math in the morning? This guy!

So, there are 9 rows of Non-Fiction books. We'll call them A-I.
A has 4 sections = A(4)
A(4) B(4) C(3) D(2) E(3) F(4) G(4) H(3) I(2)
Each section has two sides, one facing North, one South
A(N) A(S)
The 1st section of of A has 5 sets
A(S)(1)5
and each of those sets has 7 shelves
A(S)(1)5(7)
So if I select 1 book from each shelf of the South side of the 1st section of A that would be 35 books.
A(S)(1)=35
Each section has various numbers of sets and shelves but basically it adds up to this:
A=350 B=408 C=305 D=216 E=266 F=394 G=392 H=300 I=158

There are more than that. I've excluded the Espnaol selection.

So, we are left with a grand total of:
2,834 books . . .

I have a lot of work to do.
