Banking Math is set up more like a workbook than a regular book, with math problems to work on in every chapter and a handy answer section in the back. Each chapter builds on the previous ones, asking you to refer to the answers you got in order to answer new questions. This would be good, except that it does mean that you can't skip the parts you already understand. Chapter 15 is 'Putting It All Together', and asks you to figure things out using the knowledge gained plus some new variables such as using different interest rates or saving different percentages of your allowance. This section also asks you to refer to earlier answers.
I wish it had included the minimum and maximum interest rates on credit cards and on savings accounts, the difference it can make in payments, as well as WHY they can be different for different people and what can be done to change them for the better. Another section missing is information about Payday Loans and their drawbacks.
Kids are really going to be put off by the mention of check use in the checkbook section. P 20 specifically. Only old people actually carry a checkbook, so if most people forget cash and debit, they are out of luck. The only time most people use a check in a store is when they LOSE their debit card (or want to overdraft).
