Numbers Index Example 1.Natural numbers are the numbers we used in counting and they are 1, 2, 3, 4, 5, 6,.... 2.The first five whole numbers are 0, 1, 2, 3 and 4. 3.The whole numbers 0, 2, 4, 6 and 8 are examples of even numbers. They are divisible by the number 2. 4.The whole numbers 1, 3, 5, 7, 9 are examples of odd numbers. When these numbers are divided by 2, there is always a remainder 1.
7
From numbers 0 to 8, list all the (a)natural numbers,(b)whole numbers, (c)even numbers,(d)odd numbers. Index (a)Natural numbers : 1, 2, 3, 4, 5, 6, 7, 8 ( b)Whole numbers : 0, 1, 2, 3, 4, 5, 6, 7, 8 (c) Even numbers : 0,2, 4, 6, 8 (d) Odd numbers : 1, 3, 5, 7
8
Equal Set Two sets are equal if they contain exactly the same element If two set A and B are equasl, we write A = B Therefore, every elements of A is an element of B If set A is not equal to set B, we write A = B
9
Example A = {1,3,5,7} B = {3,1,7,5} Set A and B are equal A = B
10
Example A = { 2,4,6 } B = {4,6 } C = { 6,4,2 }
11
Example D = {Letters in the word ‘paper’ } E = {Letters in the word ‘pear’} D= {p,a,e,r } E= {p,e,a,r } Set D and E are equal D = E
12
Gsp – g2 การเท่ากัน Gsp – g2 การเท่ากัน Example D = {2,4,6} E = {x:x is a positive even lass than 10} E= {2,4,6,8 }
13
Home work Page 7 Which of the following represent a pair of equal 1) A = {letters in the word “ กรรมกร ” } B = {letters in the word “ มรรคา ” } C = {letters in the word “ มกราคม ” } D = {letters in the word “ รากไม้ ” }
14
Home work Page 7 Which of the following represent a pair of equal 2) E = (7,14,21,…,343} F = (x:x = 7n, n is a natural number less than 50}
15
Home work Page 7 Which of the following represent a pair of equal
16
Home work Page 7 Which of the following represent a pair of equal 4) A= {1,2,3,4,5} B= {5,4,3,2,1}
17
Home work Page 8 Which of the following represent a pair of equal 5) C = {0,1,3,7} D = {x:x is a integer number lass than10}
18
Home work Page 8 Which of the following represent a pair of equal 6) E ={12,14,16,18} F ={14,16,12,18}
19
Home work Page 8 Which of the following represent a pair of equal 7) K= {x:x is a even number less than 10} L = {2,4,6,8}
