The Habit of Self-Reliance An Independent Test by Yourself. Are you a selfreliant workman? Test yourself by practice in multiplication. Plan your own way of taking this test, how to score for speed and accuracy, and how to check your work to see if you are right. Do the work in class hours. If your teacher or Executive Committee requests it, give them your own estimate of your self-reliance. Do not be too easily satisfied. Let them check your estimate with theirs, formed on the basis of your previous class work. Are you estimating your self-reliance too high or too low? An Out-of-School Test by Yourself. Are you an honest workman? Test yourself by practice in division. If you are honest with yourself, you will be with other folks. Take this test alone. Do your work without help. Check your work alone. Score yourself. Keep the result to yourself. When you know that you are honest, don't advertise it; other folks will find it out.

PART II APPLYING THE NEW MATHEMATICS TO THE BUSINESS WORLD CHAPTER VII THE BANKING BUSINESS: INTEREST In Part I of this book we studied various ways of saving time and we drilled on these different short-cuts. In this second half we are going to apply our knowledge to the business world. Banks are the foundation of modern business. Without them trade could not be carried on as it is to-day. They keep our savings, lend us money, and make payments and exchanges easy by honoring checks. Banks use many short-cuts and time-saving devices which we have been studying in the first part of this book. There are various kinds of banks. Those chartered by the Federal Government are called national banks. State banks and trust companies get their charters from the state. Trust companies not only do a banking business, but look after property, wills, and estates. The Federal Reserve Banks act as agents for the government and do business only with other Reserve banks or banks which are members of the system. |
