Lesson 9, Monday. Word problems

• Homework 9 (word problems). Remember also to ask your parents what is necessary for salvation, and, in particular, why just deciding to believe is not enough. The key verse is "Thou believest that there is one God; thou doest well: the devils also believe, and tremble." James 2:19.

• Here is a good blog post on prayer flags and prayer wheels, with gorgeous photographs if the Himalaya Mountains. Someone came up with the idea of the "prayer wagon": drawings here and here. Relatedly, the parable of Lazarus and the Rich Man (Luke) came up in class.
• WORDS: Amiable, endless loop.

• "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.

• Homework 7 (exponents, neatness)
• Python Code

  print("Buddhist  code.")
  x = 4
  item=1
  while x<6:
  print("Glory to God in the highest!",item)
  item = item +1
  print ("The End.") 

• 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.
