1. 1. REAL NUMBERS(as opposed to fake numbers?)
2. 2. Two Kinds of Real Numbers• Rational Numbers• Irrational Numbers
3. 3. Two Kinds of Real Numbers• Rational Numbers• Irrational Numbers
4. 4. Rational Numbers• A rational number is a real number that can be written as a ratio of two integers.• A rational number written in decimal form is terminating or repeating.
5. 5. Examples of Rational Numbers•16 •-8•1/2 •1.3333…•3.56 •- 3/4
6. 6. Irrational Numbers• An irrational number is a number that cannot be written as a ratio of two integers.• Irrational numbers written as decimals are non-terminating and non-repeating.
7. 7. Examples of Irrational Numbers• Square roots of • Pi non-perfect “squares” 17
8. 8. IntegersOne of the subsets of rational numbers
9. 9. What are integers?• Integers are the whole numbers and their opposites.• Examples of integers are6-120186-934
10. 10. • Integers are rational numbers because they can be written as fraction with 1 as the denominator.
11. 11. • Integers are rational numbers because they can be written as fraction with 1 as the denominator.
12. 12. • Integers are rational numbers because they can be written as fraction with 1 as the denominator.
13. 13. Example 1:Graphing and Comparing integers.0 and -43 and - 13
14. 14. Example 2:Order the numbers from least to greatest.-0.01, 0.1, 0, 1/10 -3/5, -0.4, -1, -0.5
15. 15. Example 3Find the opposite and absolute valuea = 10 a = -7.7
