This document provides an overview of prime numbers and where they appear frequently in nature, human anatomy, and religious practices. It notes that prime numbers appear in many aspects of human anatomy like fingers, toes, bones, and ribs. Religious rituals also incorporate prime numbers, such as the five pillars of Islam, praying five times daily, and reciting dhikr seven times. Prime numbers are even found in the seven layers of the atmosphere and seven seas. Overall, the document illustrates how prime numbers pervade both the human body and spiritual practices.

6. Integers
• Integers are just like Whole Numbers; however, they contain
negative numbers as well.
• Negative Numbers are numbers smaller than 0.
• Just like Whole Numbers, Integers do not contain Fractions.
• Examples: -8, -5, 0, 4, 17, 23

7. INTEGERS
• A Number Line is used to arrange all numbers along a line.
The points on the right are greater than the points on the left.
The numbers on the Number Line are infinite, meaning they
never end and keep increasing.

13. Even numbers
• Even numbers are integers that can be completely divided
by 2.
• Even numbers can be illustrated as {…-10,-8,-6, -4, -2, 0, 2, 4,
6, 8, 10…}
• Note: Zero is considered an even number.

14. Odd numbers
• Odd numbers are integers that cannot be totally divided by 2.
• -Odd numbers can be illustrated as {…-9,-7,-5, -3, -1, 1, 3, 5, 7,
9…}
• The collection of all even and odd numbers form the set of
integers.

16. How to determine whether a number is
Even or Odd
• To determine whether a number is even or odd, notice the
number at the ones place. Like to check if the numbers 12,
15, 36, 43, 69, 88, 101, 204 are even or odd, check the ones
digit.
• An even number ends in 0, 2, 4, 6, or 8.
• An odd number ends in 1, 3, 5, 7, or 9

18. Rules of Adding/ Subtracting/
Multiplying Integers
Adding Evens and Odds
even + even = even 2 + 4 = 6
even + odd = odd 4 + 1 = 5
odd + odd = even 3 + 3 = 6
Subtracting Evens and Odds
even - even = even 8 – 6 = 2
even - odd = odd 10 – 9 = 1
odd - odd = even 5 – 3 = 2
Multiplying Evens and Odds
even x even = even 4 x 2 = 8
even x odd = even 5 x 2 = 10
odd x odd = odd 5 x 5 = 25

21. Prime Number
• A Prime Number is a positive integer which is only divisible by
1 and the number itself. For example, 7 is a prime number
because it is only divisible by 1 and 7.
• The number 6 is not a prime as it can be divided by 2 and 3.
• Note: A prime number is a whole number greater than 1.
• Some examples of Prime Numbers are 2, 3, 5, 7, 11, 13, 17, 19,
23,...

22. Properties of Primes
• Number 1 is neither a prime nor a composite number.
• Number 2 is the ONLY Even prime number and the smallest
prime too.
• All other prime numbers are odd.
• All prime numbers are positive numbers.
• Prime numbers are infinite.

23. How to find Prime Numbers
List of Prime Numbers... 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31,
37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103,
107, 109, 113, 127, 131, ...
• We can use Sieve of Eratosthenes to find Prime Numbers.
• To find all primes numbers less than 100, write all numbers
starting from 2.
• Start with 2, and cancel all multiples of 2.
• Then start with 3 and cancel all multiples of 3.
• Similarly go for 5, 7, 11. The remaining numbers are all
Primes.
23
25. Sieve of Eratosthenes
• The sieve of Eratosthenes is one of the most efficient ways to
find all of the smaller primes (below 10 million or so). It is
named after Eratosthenes of Cyrene, an ancient Greek
mathematician; although none of his works have survived, the
sieve was described and attributed to Eratosthenes in the
Introduction to Arithmetic by Nicomachus.
25
27. Composite Number
• A Composite Number can be properly divided by numbers
other than 1 or itself.
• For example, 6 is a composite number because it can be
divided by 1, 2, 3, and 6. It can be divided by more numbers (2
and 3) than just by 1 or itself.
•Note: The numbers 0 and 1 are
neither prime nor composite.
3/3/2017
27
28. Composite Numbers
• A number which has divisors other than 1 and itself are called
Composite Numbers.
• Example: 15= 1x3x5
• A composite number is defined as any number, greater than 1, that is
not prime.
• Every composite number can be written as
a product of primes. For example:
54= 2.3.3.3
Note: Except for 0 and 1, a number is
either a prime number or a
composite number.
28
29. Example
• Determine whether each number is a prime or Composite
numbers:
• 0, 2, 4, 11, 37,78,79, 90, 1.
• Prime numbers:
• Composite numbers:

60. About Seven Skies in Quran
• Seven skies is mentioned a lot in the Quran.
What is meant by those skies? “And We have
made, above you seven tracts; and We are never
unmindful of (Our) Creation.”
• In seven verses, the number of the skies is
mentioned as “seven”; in two of those verses it
is stated that the seven skies are in the form of
“layers”. (al-Mulk, 67/3; Nuh, 71/15) “Do you not
consider how Allah has created seven heavens in
layers” (Surah Nuh 71:15) 60
61. 7 Heavens: The atmosphere
has 7 layers
• Today, it is known that the
world's atmosphere consists
of different layers that lie on
top of each other. Based on
the criteria of chemical
contents or air temperature, the definitions
made have determined the atmosphere of the
earth as seven layers. As mentioned in
Qur'an (67:3) “He Who created the seven
heavens in layer”. 61
62. 7 Seas

the letter “Seen” in Persian. All these items have
a positive philosophic meaning. Others use
seven items that start with the letter “SHeen”.
Still others use seven trays (seenie) and put a
variety of items. 69

77. Ayyam al-Tashreeq
• 11th , 12th, 13th of Zilhajj (Days of Drying Meat)
• During these 3 days, (Ayyam at-Tashreeq), the pilgrims
stone the 3 pillars, from the time period between after
zawaal (sun at highest point- no shadow) until the night.
They stone all the 3 Jamarats, for which they need 21
(7x3)pebbles per day.
• Method: Throw 7 stones (one by one), saying Allahu

81. Number 19 in Quran
• The Qur'an consists of 114 (19 x 6) Suras.
• Another mathematical miracle of the Qur'an is the manner in
which the number 19 is numerologically encoded in verses.
This number is stressed in the words of the Qur'an: "There are
nineteen (angels) in charge of it." (Qur'an, 74:30), and is
encoded in various places in the Book.
81
82. NUMBER 19 in Quran
• The first Sura to be revealed, Surat al-'Alaq,
consists of 19 verses and 285 (19 x 15) letters.
• A total of 113 Suras in the Qur'an start with
Bismillah. Sura not to start with one is the ninth,
Surat at-Tawba. Surat an-Naml is the only Sura to
have two times Bismillah. One of these is at the
beginning and the other in verse 30. Counting
from Surat at-Tawba, which does not begin with
Bismillah, Surat an-Naml follows 19 Suras on.
82
83. NUMBER 19 in Quran
• The sum of all the occurrences of the name "Allah" in all the
verses whose numbers are multiples of 19 (i.e., verses 19, 38,
57, 76, etc.) is 133, or 19 x 7.
• The word "Rahman" (All-Merciful) appears 57 (19 x 3) times in
the Qur'an.
83
84. • The verse “Which of your Lord’s marvels can you deny” has
been repeated 31 times in Surah Al-Rahman which is a prime
number. The sum of all the verses numbers where it is
repeated, again gives a prime number 1433, and adding these
digits gives again 1+4+3+3=11, a prime.
84
