Ms. Hodgson, you are truly blessed with the gift of teaching. It is easy to see your excitement when teaching economics, and I think that this is the responsible factor that makes your way of teaching so captivating. Thank you again for sharing your knowledge, greetings from Brazil!
Double entry accounting is 700 years old. How hard can it be? If you search Adam Smith's Wealth of Nations for "and account" you will find multiple instances of "read, write and account".
