6. The Real Number System Natural Numbers Think ‘hide and seek’ {1, 2, 3, 4, …}

7. The Real Number System Natural Numbers Think ‘hide and seek’ {1, 2, 3, 4, …} Whole Numbers Natural numbers plus zero (Whole has an o) {0, 1, 2, 3, … }

8. The Real Number System Whole Numbers Natural numbers plus zero (Whole has an o) {0, 1, 2, 3, …} Natural Numbers Think ‘hide and seek’ {1, 2, 3, 4, …} Integers Whole numbers and their opposites (negatives) {… -3, -2, -1, 0, 1, 2, 3, … }

9. The Real Number System Whole Numbers Natural numbers plus zero (Whole has an o) {0, 1, 2, 3, … Natural Numbers Think ‘hide and seek’ {1, 2, 3, 4, …} Integers Whole numbers and their opposites (negatives) {… -3, -2, -1, 0, 1, 2, 3, … } Rational Numbers Includes the other numbers AND fractions, decimals that repeat or end -0.1234

10. The Real Number System Whole Numbers Natural numbers plus zero (Whole has an o) {0, 1, 2, 3, … Natural Numbers Think ‘hide and seek’ {1, 2, 3, 4, …} Integers Whole numbers and their opposites (negatives) {… -3, -2, -1, 0, 1, 2, 3, … } Rational Numbers Includes the other numbers AND fractions, decimals that repeat or end -0.1234 Irrational Numbers Can’t be written as a fraction Or decimals that don’t end or repeat

11. The Real Number System Summary- The real number system is broken up into 4 sets of numbers: natural, whole, integers, and rational. Sets are denoted by {} Each thing inside a set is called an element Any small set taken from a bigger set is called a subset

12. The Real Number System The set of natural numbers is {1, 2, 3, …} (Use … when you don’t want to write the whole thing)

13. The Real Number System Natural numbers are a subset of whole numbers (natural numbers is a smaller set because it doesn’t include 0, while the set of whole numbers does) What else is the set of natural numbers a subset of?

14. The Real Number System Come up with a mnemonic device to remember the order of sets of real numbers R- I- W- N-
