## Proverbs and Phrases

- "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.

- "Quis custodiet ipsos custodes", Who will guard the guards themselves?

- "A pint's a pound the world around." Thus, a pint has 16 ounces, and so does a pound.

- "Venite Adoremus": Come and let's adore, or Come let us adore him.

- "Veni, Vidi , Vici": I came, I saw, I conquered, in Latin. Julius Caesar said this.

- "Per centum": for each 100, in Latin.

- "e.g.": "exempli gratia", "for example", "as a free example", from Latin.

- "Un poème n'est jamais fini, seulement abandonné, " "A poem is never finished, only abandoned." From Paul Verlaine and W.H. Auden.

## Chapter 1: Whole Numbers

### 1.1 Counting

### 1.2 Addition

### 1.3 Subtraction

### 1.4 Multiplication and Division

### 1.5 Long Division

### Lesson 6, Friday. Order of operations, exponents

- Test 1, (arithmetic, writing numbers in words).

### Lesson 7, Wednesday. Exponents, neatness

### Lesson 8, Friday. Graphics.

- T and T Repairables, a used car dealership out west in the country.

- Homework 8 (graphics, Python)

### 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.
