Numbers Beyond 9,99,999
 Largest 6 digit number is 9,99,999.
 When we add 1 to 9,99,999 , we get 10,00,000 the smallest 7 digit number. We read it as
ten lakh.
 Largest 7 digit number is 99,99,999. We read it as ninety-nine lakh, ninety – nine thousand,
nine hundred ninety – nine.
 When 1 is added to 99,99,999 we get 1,00,00,000 the smallest 8 digit number. We read it
as one crore.
 The largest 8 digit number is 9,99,99,999. We read it as nine crore, ninety-nine lakh,
ninety-nine thousand, nine hundred ninety-nine.
 When 1 is added to this number, we get 10,00,00,000 the smallest 9 digit number. We read
it as Ten Crore.
Indian Place Value Chart
 To make it easy to read and write the large numbers, the Indian Place Value Chart has been
divided into periods.
 The First Period is the ONES PERIOD with three places- Once (0), Tens (T) and Hundreds
(H)
 Second period is the THOUSANDS PERIOD with two places –Thousand (Th) and Ten
Thousands (TTh)
 Third period is the LAKHS PERIOD with two places – Lakhs (L) and Ten Lakhs (TC)
 Fourth Period is the CRORES PERIOD with two places –crores (C) and Ten Crores (TC)

 While reading a number all the digit in the same period are read together and the name of
the period(expect the ones is read along with them).
 While writing a number ,we usually put a comma after every period to separate the periods.
 The plural of periods is not written. For example instead of writing five crores, three lakhs ,
ninety –four thousands, six hundreds eighty –one, we write five crore, three lakh, ninety –
four thousand, six hundred eighty – one.

FACE VALUE AND PLACE VALUE
 Face Value : The face value of a digit is always the digit it self.
For example, face value of 5 in 74,58,962 is 5 only.
Face value of 2 in 42,58,973 is 2 only.
 Place Value : Place value of a digit depends on the place it occupies in the place value
chart.
Place value = Face Value X Value of the place
Place values of the digits of 92,14,67,352 are:
921467352
2x1=2
5 x 10 = 50
3 x 100 = 300
7 x 1000 = 7000
6 x 10000 = 60000
4 x 100000 = 100000
1 x 1000000 = 1000000
2 x 10000000 = 20000000
9 x 100000000 = 900000000
 Place value of 0 is always 0 whatever place it may occupy.
Successor of a number : The number that comes just after a given number is
called its successor.
Eg : Successor of 78,69,599 = 78,69,599 + 1 = 78,69,600
Predecessor of a number : The number that comes just before a given number
is called its predecessor.
Eg: Predecessor of 5,68,74,956 = 5,68,74,956 – 1 = 5,68,74,955
FORMATION OF THE GREATEST AND THE SMALLEST NUMBERS :
 To form the greatest number, arrange the given digits in the descending order.
 To form the smallest number, arrange the given digits in ascending order.
 Zero should never be the 1st digit in the extreme left. To get the smallest number, zero
should always be the 2nd digit from the left.
 Fro Eg : Form the greatest and the smallest numbers from the digits 2,0,1,7,3 and 4 .
The greatest number = 743210
The smallest number = 102347

MULTIPLICATION
 Following terms are used in Multiplication.
1.Multiplicand : The number to be multiplied is called the multiplicand.
2.Multiplier : The number by which we multiply is called the multiplier.
3.Product : The result we obtain after the multiplication is called the product.
E.g.: 6 2 Multiplicand
X 5 Multiplier
3 1 0 Product
Properties of Multiplication
1.Order Property : The product of two numbers do not change when the order of the
number is changed. For Eg. 5 X 8 = 40 and 8 X 5 = 40
So, 5 X 8 = 8 X 5
2.Multiplicative property of 1 : The product of a number and 1 is the number itself .
For eg. 27 X 1 = 27, 159 X 1 = 159 , 1234 X 1 = 1234
3.Multiplicative property of 0 : The product of a number and 0 is 0.
For eg. 199 X 0 = 0, 5432 X 0 = 0

DIVISION
Terms used in Division :
1.Dividend : The number to be divided is called the dividend.
2. Divisor : The number by which we divide the dividend is called the divisor.
3. Quotient : The result of division is called quotient.
4. Remainder : The number which is left undivided is called the remainder.

PROPERTIES OF DIVISION
1.The following relationship holds good in a division :
Dividend = Quotient X Divisor + remainder
This relationship is used to check the division.
2.When a number expect 0 is divided by itself the quotient is 1
For Eg : 25 / 25 = 1,
339 / 339 = 1
3. When a number is divided by itself, the quotient is 1.
For Eg : 29 / 1 = 29
909 / 1 = 909
4. When 0 is divided by a number expect 0, the quotient is 0.
For Eg : 0 / 23 = 0
0 / 157 = 0
5. A number cannot be divided by 0.

CH-11 ROMAN NUMERALS
* There are seven distinct symbols in Roman system. They are
Roman Numerals

V

L
C
D
Hindu Arabic Numerals

100 500
(4) d

(10) c

 There is no zero in the Roman System.
 This system has no place value system.
RULES
1) Repetition of a symbol means addition.
For Eg. 111 = 1 + 1 + 1 = 3
XXX = 10 + 10 + 10 = 30
CC = 100 + 100 = 200
 Repetition is not allowed more than 3 times.
 V , L & D are never repeated.
2) If a smaller number is written to the right of a greater numberal then the smaller is added to
the larger one.
For Eg. VII = 5 + 1 + 1 = 7
XI = 10 + 1 = 11
LXXX = 50 + 10 + 10 +10 = 80
CLX = 100 + 50 + 10 = 160
3) If a smaller numeral is written to the left of a larger numeral the smaller is always
subtracted from the larger one.
For Eg. IV = 5 – 1 = 4
IX = 10 – 1 = 9
XL = 50 – 10 = 40
XC = 100 – 10 = 90
 The numerals V , L and D are never subtracted.
 I is never written to the left of L, C and D.

BASIC GEOMETRICAL CONCEPTS
1. POINT : A small dot made by a sharp pencil on a piece of paper represents a point.

A
 A point has no length no breath and no thickness.
 It has only position.
 It is represented by capital letters such as A, B, C, X, Y, Z etc.
2.LINE SEGMENT : The straight path between two given points is called line
segment.
 A line segment has a fixed length.
 A line segment AB is denoted as AB.
 Points A & B are end points of AB.
 Line segment AB is same as BA.
3.LINE : A line segment extended endlessly in both the directions is called a line.
 It has no end points.
 It is denoted by AB.
 AB is same as BA.
 A line has no definite length.
4. RAY : A line segment extended endlessly in one direction is called a Ray.
 It has one end point. In the fig.A is the end point of Ray AB. It is also called the initial
point of AB.
 It is denoted as AB.
 It has no definite length.
 Ray AB is different from BA.
5. INTERSECTING LINES : When two lines meet at a point, then they are called intersecting
lines and the point at which they meet is called point of intersection.
Here AB and CD are intersecting
Lines and O is the point of intersection.
6. COLLINEAR POINTS: When three or more points lie on the same line, then they are said to be
collinear.
In the fig A, B, C are collinear but
D, E, F are not collinear.
EXERCISE 21 A
Q : 1 Classify the following as Point, Ray, Line and Line Segment.

Q : 5 In the figure name the following.
a) 4 line segments
b) 3 rays
c) 2 lines
d) 4 collinear Points
Q : 6 In the figure name
a) 2 Pair of intersecting lines
b) 4 collinear points

1) A line segment has _____________________ end points.
2) A ray has ___________________ end point.
3) A ____________________ has a fixed length.
