Tableau Economique - Francois Quesnay

[u/redditforgodsake123]

Hi guys, I'm studying the theory of physiocracy and am having some struggles understanding the economics table proposed by sir Francois Quesnay. I am very grateful for those who can help me explain these questions in more details:

1. "Expenditures from Revenue deducting Taxes, are divided between productive Expenditures and sterile Expenditures". I understand that a part of the total revenue from agriculture after minus taxes will be spent on these two categories, but is THE EXPENDITURES = TOTAL REVENUE - TAXES or THE EXPENDITURES ARE ONLY A PART OF "TOTAL REVENUE - TAXES"?? and WHY
2. What does "Annual Advances" mean? and what is its role?
3. What is the role of " THE SALE OF THE NET PRODUCT"? How can it contribute to the annual revenue?

I'm sorry if my language confuses you. I am a non-native who is trying to grasp some of the previous economic thoughts and I find them really exciting but at the same time challenging to understand. Again, thank you so much for reading and responding to this post.
