This document provides an overview of different number systems and concepts in mathematics related to numbers. It defines real numbers, rational numbers, integers, whole numbers, and natural numbers. It discusses that rational numbers can be divided into integers, whole numbers, and natural numbers. Irrational numbers are also introduced. Important mathematicians who contributed to the study and understanding of numbers are referenced, including Pythagoras, Archimedes, Aryabhatta, Dedekind, Cantor, Babylonians, and Euclid.
Rational numbers are numbers that can be represented as fractions p/q where p and q are integers and q is not equal to 0, such as 2/5 or 4/7. Irrational numbers are numbers that cannot be represented as fractions, such as √2 or √3, and their decimal representations are non-terminating and non-repeating. Real numbers include both rational and irrational numbers and can all be represented as unique points on a number line, with rational numbers having either terminating or non-terminating repeating decimals and irrational numbers having non-terminating, non-repeating decimals.
This is meant for age group 11 to 14 years.

The document provides an overview of number systems throughout history. It discusses how ancient civilizations like the Egyptians and Babylonians experimented with different bases like base-12 and base-60 systems. It then covers the decimal system and describes number types like rational, irrational, integer, natural numbers and their properties. The document also discusses concepts like fractions in ancient Egypt, binary numbers and the expansion of numbers into terminating, non-terminating recurring and non-recurring decimals.
Mathematics is essential in daily life and has a long history of practical applications. It first arose from needs to count and measure, and early civilizations used math for tasks like construction and accounting. Over millennia, mathematical concepts and applications have expanded greatly. Today, areas like statistics, calculus, and other quantitative fields inform domains from politics to transportation to resource management. Many people misunderstand math as only involving formulas, but it really involves abstract problem-solving and modeling real-world situations. Core topics in daily use include commercial math, algebra, statistics, and financial calculations for tasks like budgeting and investing.
Mathematics guides all sciences and social sciences by providing principles and models. During the 19th century, mathematics was seen as abstract but it is now widely applied across many fields from engineering to genetics due to developments in applied mathematics spurred by World War 2 and Sputnik. Modern technologies like CAT scanners and economic models all depend on sophisticated mathematical foundations. Engineering in particular utilizes differential equations, geometry, and other areas of mathematics.
This document discusses polynomials and some key concepts related to them. It defines what a polynomial is and explains that they can be categorized as monomials, binomials, or trinomials depending on the number of terms. It also discusses the degree of a polynomial, which is the highest power of the variable. Other topics covered include standard form for writing polynomials, the remainder theorem, and the factor theorem.
This document defines and explains different types of numbers:
1. Natural numbers are the positive whole numbers {1, 2, 3...}. Whole numbers include 0. Integers include positive and negative whole numbers. Rational numbers can be written as fractions. Irrational numbers cannot be written as fractions.
2. Real numbers include rational and irrational numbers and can be written as decimals. Complex numbers are numbers in the form a + bi, where a and b are real numbers. Complex numbers contain both real and imaginary parts.
3. The set of complex numbers contains all real and imaginary numbers. Operations on complex numbers follow specific rules: addition/subtraction combine real and imaginary parts separately, multiplication distributes and
The document defines several subsets of real numbers including natural numbers, whole numbers, integers, rational numbers, and irrational numbers. It provides examples for each set and discusses their properties. Rational numbers can be expressed as terminating or repeating decimals while irrational numbers are expressed as non-terminating, non-repeating decimals. The document also covers topics like the Euclid division algorithm, fundamental theorem of arithmetic, finding the highest common factor and least common multiple of numbers.
Coordinate geometry is a system that describes the position of points on a plane using ordered pairs of numbers. Rene Descartes developed this branch of mathematics in the 17th century. A coordinate plane has two perpendicular axes (x and y) that intersect at the origin point (0,0). The distance between any two points on the plane can be calculated using the Pythagorean theorem. The midpoint and points of trisection of a line segment can be found using section formulas, as can the coordinates of the centroid of a figure.
This document discusses Vedic mathematics, an ancient system of mathematics originally developed in India. Some key points:

There are several commonly used diagrams to represent numerical data, including pictographs, bar graphs, double bar graphs, and pie charts. Pictographs use symbols or pictures to represent data, with each symbol representing a certain value. Bar graphs display data using uniformly wide bars of varying heights. Double bar graphs show two sets of data simultaneously. Pie charts, also called circle graphs, show the relationship between a whole and its parts by dividing a circle into sectors proportional to the parts.
Real numbers comprise all numbers that can be used in everyday life, including natural numbers, whole numbers, integers, rational numbers, and irrational numbers. Real numbers represent unique points along the infinite number line. They include natural counting numbers and their positives, whole numbers with zero added, integers with their positives and negatives, rational numbers that can be written as fractions, and irrational numbers with non-terminating, non-repeating decimals.
Here are the steps to find 5/7 + 3/7 using appropriate properties:
1) Find a common denominator for 5/7 and 3/7:
The common denominator is 7
2) Convert 5/7 and 3/7 to equivalent fractions with the common denominator of 7:
5/7 = 5/7
3/7 = 3/7
3) Add the numerators:
5/7 + 3/7 = 8/7
4) Simplify if possible:
8/7 cannot be simplified.
Therefore, 5/7 + 3/7 = 8/7

This document summarizes research on multiple sclerosis (MS). MS is a chronic disease that attacks the central nervous system. While the exact cause is unknown, it is believed to involve genetic and environmental factors. The most common form is relapsing-remitting MS, where neurological symptoms flare up and then decrease. Several drugs are used to treat MS and reduce relapse rates, but many have side effects. Ongoing research aims to better understand MS and develop safer, more effective treatments.

4. Conclusion: A number is an idea and the numeral is how we write it.
DIGIT
NUMERALS
Number Systems
DIGIT is a single
symbol used
alone or in
combinations to
make Numerals.
e.g. 0, 1, 2, 3, 4, 5,
6, 7, 8, 9
Numerals: A group of digits or signs or symbols or
name that stands for a number are called Numerals.
(संख्यांक:- संख्या को तनर्देलिि करने वाले अंकों अथवा संक
े िों
क
े समूह को संख्यांक कहा
िािा है|) e.g. 3, 49 and twelve are all numerals.
Let me explain, 3 is single digit but also a numeral.
Similarly, 49 is also a numeral but with two digits i.e.
4 & 9.
Also, forty nine is a numeral as it is name for 49.

Number Systems
प्राकृ ि संख्याएँ
All counting numbers are called Natural Numbers denoted by N.
E.g. 1, 2, 3, 4, 5, 6, 7 ,. . . . ∞ (to infinity).
Note:-
Natural numbers are always positive ( धनात्मक ).
1 is the smallest ( सबसे छोटी ) natural number.
0 “Zero” is not a natural number.

Number Systems
पूर्ण संख्याएँ
All counting numbers including zero are called Whole Numbers denoted by W.
E.g. 0, 1, 2, 3, 4, 5, 6, 7 ,. . . . ∞ (to infinity).
Note:-
Every natural number is whole number.
0 is the smallest ( सबसे छोटी ) whole number.
0 “Zero” is the starting number in whole numbers.
यदर्द प्राकृ ि संख्याओ में िून्य (0) को सजममललि कर ललया िाए, िो वे संख्याएँ पूर्ण संख्याएँ कहलािी हैं|
Or प्राकृ ि संख्या क
े समूह में िून्य को सजममललि करने पर िो संख्याएँ प्राप्ि होिी हैं, वे ‘पूिण संख्याएँ’ कहलािी हैं|
िैसे- 0, 1, 2, 3, 4, 5, 6, 7, . . . ∞
9. INTEGERS

Number Systems
पूर्ाणक संख्याएं
All counting numbers including zero and negatives of the counting numbers are called Integers
denoted by I.
E.g. -∞…….., -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7 ,. . . . ∞ (to infinity).
Note:-
Integers are both positive and negative.
Zero (0) is neither a positive nor negative integer number.
I+ and I- are denoted as positive and negative integers ( धनात्मक और ऋिात्मक पूिाांक संख्या)
पूिण संख्याओ में ऋिात्मक संख्याओं को सजममललि करने पर िो संख्याएँ प्राप्ि होिी है वे संख्याएँ पूर्ाणक

Number Systems
सम संख्याएँ
Numbers which are completely divided by 2 are called Even Numbers.
E.g. 2, 4, 6, 8, 10, 12….so on.
वे संख्याएँ िो 2 से पूिणिः ववभाजिि हो िािी हैं उन्हें ‘सम संख्याएँ’ कहिे हैं|
िैसे 2, 4, 6, 8, 10, 12….so on.
11. ODD NUMBERS
5
Number Systems
विषम संख्याएँ
Numbers which are not completely divided by 2 are called Odd Numbers.
E.g. 1, 3, 5, 11, 17, 29, 39 ….so on.
वे संख्याएँ िो 2 से पूिणिः ववभाजिि नह ं होिी है, उन्हें ‘विषम संख्याएँ’ कहिे हैं|
िैसे 1, 3, 5, 11, 17, 29, 39 ….so on.
12. PRIME NUMBERS
6
Number Systems
अभाज्य संख्याएँ
Natural numbers having only two factors i.e. 1 and itself.
Or Those numbers which are not divisible by any number other than themselves and 1,
are called Prime Numbers.
E.g. 2, 3, 7, 11, 13, 17, 19…. So on.
वे संख्याएँ िो स्वयं और 1 क
े अलावा अन्य ककसी संख्या से ववभक्ि नह ं होिी हैं उन्हें ‘अभाज्य संख्याएँ’ कहिे हैं।
Let me explain with an example, suppose we have 13 and we look for its factor we found
that it has only two factors.
Factors of 13 are 1 & 13 itself.
Note: -
1 is neither a Prime Number nor a Composite Number.
There are twenty five (25) prime numbers between 0 to 100.
13. COMPOSITE NUMBERS
7
Number Systems
भाज्य संख्याएँ
Those numbers which are completely divisible by any number other than themselves and 1,
are called Composite Numbers.

वे संख्याएँ िो स्वयं और 1 क
े अतिररक्ि ककसी अन्य संख्या से पूिणिः ववभाजिि होिी है, िो
वह भाज्य संख्या कहलािी है|
Let me explain with an example, suppose we have 9 and we found that it has three factors
i.e. 1, 9, 3.
9 = 1 X 9, 3 X 3
Note: -The composite number is both even and odd.
14. CO-PRIME NUMBERS
8
Number Systems
सह-अभाज्य संख्याएँ
When there is no common factor except 1 in a group of two or more numbers, or whose HCF
(Highest Common Factor) = 1, they are called Co-Prime Numbers.
Or
Pairs (pairs) of numbers that do not have any common factors other than 1 in their factors
are called co-prime numbers.
Like- (4, 9), (12, 25), (8, 9, 13) etc.
िब र्दो या र्दो से अगधक संख्याओं में कोई भी उभयतनष्ठ गुिनखंड न हो अथवा जिसका म.स. 1 हो ,वे एक साथ ‘सह-
अभाज्य संख्याएँ’ कहलािी हैं।
15. RATIONAL NUMBERS

पररमेय संख्याएँ
Denoted by “Q” are numbers which can be written in p/q form, where p and q are integers and
q≠ 0.
वह संख्या िो p/q क
े रूप में ललखा िा सकिा है, उसे पररमेय संख्या कहिे है , िहाँ p िथा q पूिाांक हैं एवं
q ≠ 0 अथाणि p और q र्दोनों पूिाांक हो लेककन q कभी िून्य न हो.
िैसे- 4, 1.77 , 0 , 2/3 आदर्द|
17. IRRATIONAL NUMBERS
10

अपररमेय संख्याएँ
A number that cannot be written as p / q is called an irrational number.
Where p and q are integers and q ≠ 0
Like - √2, 5 + √3, √2, 5 1/3, π… ..
Note: -π is an irrational number.
वह संख्या जिसे p/q क
े रूप में नह ं ललखा िा सकिा है, वह अपररमेय संख्या कहलािी है.
िहाँ p िथा q पूिाांक हैं एवं q ≠ 0
िैसे – √2, 5 + √3 , √2 , 5 1/3 , π …..
19. REAL NUMBERS

Number Systems
िास्िविक संख्याएँ
Real numbers include all rational and all irrational numbers. Denoted by “R”
e.g. 4 , 6, 2 ,√7, +4 , -2 etc.
Note:- The actual number is denoted by Rez or R.
सभी पररमेय िथा अपररमेय संख्याएँ ‘िास्िविक संख्याएँ’ कहलािी हैं।
20. IMAGINARY NUMBERS
12
Number Systems
काल्पतनक संख्याएँ
These numbers are complex numbers which can be written as real number multiplied by an imaginary
unit “i”called Imaginary Numbers.
Square root of a negative number where it doesnot have definite value.
Such as: −2 and −5 etc.
Note: -
The imaginary number is denoted by Imz.
The imaginary number when squared results in negative number.
ऋिात्मक संख्यायों का वगणमूल लेने पर िो संख्याएं बनिी हैं , उन्हें काल्पतनक संख्याएं कहिे हैं ।
