1. Real Number System Homework on Approximating Square Roots

2. Real Number System… Real Numbers are made up of 5 different sets of numbers: – Natural Numbers – Whole Numbers – Integers – Rational Numbers – Irrational Numbers

3. Natural Numbers Whole Numbers Irrational Numbers Rational Numbers Integers 1, 2, 3 ….. Counting Numbers ANY number than can be rewritten as a fraction of integers, 0, -1, 2, 9, -1.010010001, π, ANY number than can NOT be rewritten as a fraction of integers -3, -2, -1, 0, 1, 2, 3….. Natural Numbers + Zero 0, 1, 2, 3 ….. Natural Numbers + Their Opposites + Zero

4. What category/categories would the following numbers belong in? 0 -7.34 π Integer, rational Rational Irrational Whole, integer, rational Rational Natural, Whole, Integer, Rational Irrational

5. Try to label the correct number systems on your diagram: Hint: Which system is NOT like any of the others? Which system has the most limitations? Natural, Whole, Integers, Rational, and Irrational

6. How many did you correctly label?

7. Now place the following numbers into the correct number system on the diagram:
