What made a lot of Econ and related stuff click for me is the idea that there is no such thing as a sale, only a purchase. When you buy a tv for $200, the electronics store buys $200 dollars of cash for $200 of TV.
So the electronic store hasn’t made any money on the transaction. They lost $200 dollars of tv and received $200 of cash. So the tv account got deducted 200 and the cash account got increased 200.
