Example text

You can say, “Well, that can be debated. ” That should get you a raised eyebrow. ) and scribble out the following to make your point: 0=∅ 1 = {0} = {∅} −1 = {0, 1} = {∅, {∅}} 2 = {0, 1, −1} = {∅, {∅}, {∅,{∅}}} −2 = {0, 1, −1, 2} = {∅, {∅}, {∅, {∅}},{∅, {∅}, {∅, {∅}}}} ↓ and so on, forever Are you confused? The integers can get confusing when you compare values. If you draw a number line and represent the integers as points on it, such as is done in Figs. 3-4 or 3-5, what does it mean if one number is “larger” or “smaller” than another?

If you have a basket full of apples and you call it a set, is it still a set when you dump the apples onto the ground? Were those same apples elements of a set before they were picked? Questions like this can drive you crazy if you let them. A collection of things is a set if you decide to call it a set. It’s that simple. As you go along in this course, you’ll eventually see how sets are used in algebra. Here’s an easy example. What number, when multiplied by itself, gives you 4? The obvious answer is 2.

Consider a billion as a thousand million, and a trillion as a million million. 5. How many ciphers could you add to the left of the digit 3 in the decimal numeral in the situation of Problem 4 without changing the value of the number it represents? 6. How can you make the number represented by the numeral in the answer to Problem 4 ten times as large? A hundred times as large? A thousand times as large? 7. How can you write out the final answer to Problem 6 as a number in words rather than as a numeral in digits?
