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
The Real Number System
• The set of natural numbers is {1, 2, 3, …}• (Use … when you don’t want to write the whole
thing)
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?
The Real Number System
• Come up with a mnemonic device to remember the order of sets of real numbers
• R-• I-• W-• N-
Applying it
• 3/8 is an element of which sets of real numbers?
• Rational
Applying it
• 5 is an element of which sets of real numbers?
• Rational, Integers, Whole, Natural
Applying it
• 0 is an element of which sets of real numbers?
• Rational, Integers, Whole,
Applying it
• 700 is an element of which sets of real numbers?
