How To Determine The Location Of Numbers In The Line Of Numbers
Determining the Location of Numbers on the Numbers - Meet again Basic Mathematical Formulas . This time we will study together about the number line. Do you know what a number line is? The number line is a line on which the lines are placed in sequential or sequential numbers ranging from the smallest to the largest. Basic skills that you must master before studying the matter of this line of numbers is you must know in advance how to sort in sequence. Spelling out means to say numbers in sequence. That is, you must be able to determine a number ranging from the smallest to the largest. Examples are 1, 2, 3, 4, 5, 6, etc. That is one example spelled out in sequence. Now consider the picture of the line of numbers below:
On the number line above we can see that the more to the right of the number will become larger The right-handed number will always be greater than the number on the left.It's the fundamental way you should understand about the location of a number on the number line.
Sorting And Comparing Two Numbers
Now that you know how to sort and place the number on the number line, we now proceed with the material on how to compare between one number with another.
Compare the numbers on the line of numbers whether smaller or larger than the other numbers. As explained above that when writing numbers on the line of positions the numbers must be sequential from small to larger numbers. The number on the left will be smaller than the number on the right. So that the number to the left of its value "Less Than" is the number that is on the right. Meanwhile, the number that is to the right of its value "More Than" the number that is to his left.
Observe the following examples:
In a number line in the top 32 in value "less than" 33 for the top 32 on the left side of 33 Or can be written to 32 <33 (32 less / less than 33)
Meanwhile, 39 values "more than" 38 for the number 39 located on the right side of 38, or can be written to 39> 38 (39 is greater than 38)
Determining Numbers Located Among Two Numbers
Gilang, Amir, and Wayan are members of the basketball team. In a tournament, Amir and wayan come early. They each got back numbers 54 and 56. Gilang obtained his back number before Wayan and after Amir. What is the number of backs obtained by Gilang?
The above problem can be solved by using the following number line:
From the number line above it can be seen that the number whose position after 54 and before 56 is 55, then the back number obtained by Gilang is 55.

Assessing the Numbers Specified in Numbers
Try you Specify any number that fills the positions a, b, and c on the line of numbers below:
Perhatikan dengan baik bahwa 2 dengan 4 selisihnya adalah 2 , 4 dengan 6 selisihnya juga 2 maka:
a = 6 + 2 = 8
b = 12 + 2 = 14
c = b + 2 = 14 + 2 = 16
Pola pada Barisan Bilangan
Barisan bilangan memiliki pola-pola tersendiri contohya:
Bilangan asli = 1, 2, 3, 4, 5, 6, ...
Bilangan ganjil = 1, 3, 5, 7, 9, 11 ...
Bilangan genap = 2, 4, 6, 8, 10, 12, ...
Setiap bilangan yang ada pada barisan bilangan disebut sebagai suku barisan.
Suku ke-1 pada bilangan asli adalah 1
Suku ke-1 pada bilangan ganjil adalah 1
Suku ke-1 pada bilangan genap adalah 2
Suku ke-2 pada bilangan asli adalah 2
Suku ke-2 pada bilangan ganjil adalah 3
Suku ke-2 pada bilangan genap adalah 4
Nil ai selisih pada barisan bilangan tersebut berbeda-beda maka memiliki rumus tersendiri untuk menentukan sukunya.
Karena selisih pada barisan bilangan asli adalah 1 pada setiap sukunya, maka rumus untuk menentukan suku berikutnya adalah ditambah dengan 1.
Misalkan suku ke-5 = suku ke-4 + 1 = 4 + 1 = 5
Karena selisih pada barisan bilangan ganjil adalah 2 pada setiap sukunya, maka rumus untuk menentukan suku berikutnya adalah ditambah dengan 2.
Misalkan suku ke-6 = suku ke-5 + 2 = 9 = 2 = 11
Nah kurang lebih begitulah penjelasan sederhana mengenai Cara Menentukan Letak Bilangan Pada Garis Bilangan untuk mengetahui penjelasa n lebih lanjut mengenai pola bilangan, silahkan simak materi yang berjudul Pola Bilangan Matematika Ganjil dan Genap .
