• "When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years." Mark Twain, "Old Times on the Mississippi," Atlantic Monthly, 1874.

• Steps in solving word problems: 1. Figure out what the question is and what kind of number is supposed to be the answer. 2. Figure out which numbers in the question are relevant--- some numbers might well be irrelevant to getting to the answer. 3. Figure out what techniques you are going to need, e.g., addition, division, Python coding, looking up something on the Internet.
