Lesson- Operation on Whole numbers ( Multiplication and

Division)

Multiplication of Large Numbers( Write terms and properties in c.w copy)

As we know, multiplication is the short way to do repeated addition.

Multiplier- The number by which any number is multiplied. Multiplicand -The number to be multiplied . Product - The result of the multiplication.

Example 1. Multiply 76432 by 5245. Solution.

Properties of multiplication: 1. Closure property:

For any two whole numbers a and b,their product ax b is always a whole number. E.g. 12 x 7 = 84, 12, 7 and 84 all are whole numbers. 2. Commutative property:

For any two whole numbers a and b, a x b = b x a ,Order of multiplication is not important. E.g 11 x 6 = 66 and 6 x 11 = 66 Therefore, 11 x 6 = 6 x 11

3. Associative property:

For any three whole numbers a, b and c, (a x b) x c = a x (b x c), this means the product is regardless of how grouping is done. E.g 8 x (4 x 5) = 8 x 20 = 160; (8 x 4) x 5 = 32 x 5 = 160 Therefore, 8 x (4 x 5) = (8 x 4) x 5

4. Multiplicative identity:

For any whole number a, a x 1 = a

Since any number multiplied by 1 doesn’t change its identity

hence 1 is called as multiplicative identity of a whole number. E.g. 21 x 1 = 21

5. Multiplication by zero:

For any whole number a, a x 0 = 0, E.g 25 x 0 = 0

6. Distributive property of multiplication over Addition and subtraction

For example: (i) (18+ 15) × 5 = 18 × 5 + 15 × 5

(ii) (18 – 15) × 5= 18 × 5 – 15 × 5 (iii) 172 x 97 =172 x (100-3) {as 97=100-3} = 172 x 100 - 172 x 3 = 17200 - 516= 16684 Rules for the multiplication by 10, 100 and 1000:And their multiples

*To multiply a number by 10, 100, or 1000 we need to count the number of zeroes in the multiplier and multiplicand and write the same number of zeroes to

the right of the product. For example: (i) 750× 10 = 7500 (ii) 234 × 100 = 23400 (iii) 1692 × 10000 = 16920000

*To multiply a number by 2000, 3000 or 4000 and so on, we multiply the number by the digit in the thousands place of the multiplier and write the three zeros on the right of the product. For example: (i) 735 × 6000 = (735 × 6) × 1000

= (4410) × 1000 = 4410000

Multiplication by rearranging By rearranging the order of the numbers,

multiplication becomes easy. We try to combine the numbers that produce maximum number of zeros after the multiplication. Remember- 2 x5=10 25 x 4 =100 20 x 5 = 100 50 x 2 = 100

125 x 8 = 1000 Ex- 25 x 4581x 4= 4581x(25x4) =4581 x 100= 458100

Division of Large Numbers We already know about division as repeated subtraction, equal sharing and inverse of multiplication.

Divide 86228364 by 2768 and check the answer.

Now to check the answer of the division: Dividend = Divisor × Quotient + Remainder, remainder<divisor 86228364 = 2768 × 31151 + 2396 86228364 = 86225968 + 2396 86228364 = 86228364

Terms of division Dividend: The number that is being divided. Divisor: The number that divides another number. Quotient:The answer of division. Remainder: The number left after division, it is always less than divisor.

Properties of division Division does not follow closure, commutative and associative properties. E.g. 68 and 5 are whole numbers but 68 ÷ 5 is not a whole number. E.g. 16 ÷ 4 ≠ 4 ÷ 16 E.g. consider (80 ÷ 10) ÷ 2 = 8 ÷ 2 = 4 80 ÷ (10 ÷2) = 80 ÷ 5 = 16 (80 ÷ 10) ÷ 2 ≠80 ÷ (10 ÷2)

Division by 1

For any whole number a, a ÷ 1 = a, E.g. 14 ÷ 1 = 14; 26 ÷ 1 = 26 Division by number itself

If we divide a number by itself (except zero), the quotient is 1. E.g: 276÷ 276=1 Division of 0 by any whole number

For any whole number, a ≠ 0, 0 ÷ a = 0, this shows zero divided by any whole number (other than zero) gives the quotient as zero. E.g. 0 ÷ 1 = 0;

0 ÷ 25 = 0; Division by 0

It is not possible to divide any number by 0. Therefore, division by 0 is not defined. Eg: 56÷ 0= not defined Division by 10,100,1000

When a number is divided by 10,100,1000 etc.., remainder digits will be equal to number of zeros. Ex- 67305÷ 10= Q=6730 , R =5 67305÷ 100=Q=673,R= 05 67305÷ 1000=Q=67,R=305

Exercise (Do it in c. w copy) 1. Find the product by distributive property a) 241 x 107 b) 685 x 94 2. Rearrange the numbers and then multiply them a) 625 x 25 x 20 x 4 b) 20 x 1975 x 5

3. Find the missing multiplicand (i) ……………… × 40 = 36000 (ii) ……………… × 500 = 7500000 4. Book exercise 3 (C) question no. 1- a and c Question no.-2-g,I

Movement in animals –

Animals move from one place to another in search of food , shelter and to escape from

their enemies. Different animals have different types of adaptations for movement.

Dogs, cats , lion and human beings move with the help of their legs.

Snakes move on the ground with the help of their body muscles and ventral scales.

Fishes move with the help of their fins. While frogs use their back legs to hop and

their webbed feet to swim.

Birds can fly with the help of their wings. They also use their legs to move or hop.

Animals like penguins and seals swim with the help of their flippers.

Flippers for swimming Fins for swimming

Seal Penguin A fish

Migration- The periodic mass movement of birds and animals from one place to another

and back to their original homes is called migration.

The animals migrate from one place to another in search of food, to protect themselves

from harsh weather conditions and for better breeding grounds. Some examples are :-

1) The Siberian Crane nests near the north pole in summer and flies all the way to

India in autumn to escape harsh cold conditions.

2) Salmon fish migrate from saltwater to freshwater for reproduction.

3) Monarch butterflies, which are native of North America, migrate to southern parts

of California to spend the winter season.

4) Dragonflies migrate to southern part of Asia during winter seasons.

5) African elephants migrate in search of food during changes in resource availability.

LESSON 2: PARALLELS AND MERIDIANS [Contd…] TOPICS:-

MERIDIANS (INTRODUCTION)

MERIDIANS AND ITS FEATURES HOW ARE MERIDIANS NUMBERED?

LOCATING PLACES ON THE GLOBE. ** MERIDIANS (INTRODUCTION):

Imaginary lines running from north to south are

called meridians or lines of longitude.

These lines are drawn from north pole to south pole.

**MERIDIANS AND ITS FEATURES:

All meridians are of same length.

The maximum distance between any two meridians is at the Equator.

The distance between any two meridians decreases as we move away

from the Equator towards the poles.

Meridians cut the parallels at the right angles.(90 ͦ)

Meridians are used to measure distances in the east-west direction. **HOW ARE MERIDIANS NUMBERED?

In 1884, it was decided to fix Greenwich, a place near

London, as the starting point for numbering meridians.

The meridian that passed through Greenwich was

marked 0ͦ and named Prime Meridian.

The longitude of a place is measured east or west of the Prime Meridian.

Like parallels, Meridians are also drawn at intervals of

one degree.

There are 180 meridians towards the east of the Prime Meridian and 180 meridians towards the west of the

Prime Meridian.

The meridians of 180 ͦ E and 180 ͦ W is the same line.

So, in total there are 360 meridians.

**LOCATING PLACES ON THE GLOBE:

The parallels and meridians form a network of lines on the globe. This is called a grid. It is used to locate places on the globe.

THE ROYAL OBSERVATORY, GREENWICH

ROYAL PARK, LONDON, UK.

THE GREENWICH MERIDIAN LINE

The point at which the parallel and meridian cross each other is the location of that place.

To locate a place on the globe, we must know the values of its latitude and

longitude.

BLOCK DIAGRAM OF COMPUTER:

Computer works on the principle of IPO(INPUT-PROCESS-OUTPUT)

cycle.

Computer devices are broadly divided into 3 parts:-

1. INPUT DEVICES:- Input devices takes input from the users and

feed the data and information to a computer.

Examples are:-

Keyboard, mouse, graphic tablet, light pen, microphone,

webcam, joystick etc.

2. OUTPUT DEVICES:- An output devices displays the result of the

input after it has been processed. Example are:- Monitor,

printer, plotter and speakers.

3. PROCESSING DEVICES:- CPU IS THE PROCESSING DEVICE OF A

COMPUTER.

CPU stands for central processing unit.

It has three main components-

1. CONTROL UNIT- This unit co-ordinate various operations of

computer.

2. ARITHMATIC LOGIC UNIT-This unit is responsible for various

operations like-addition, subtraction, multiplication, division

and logical operation.

3.MEMORY UNIT-It stores the information in the form of

instructions and data. It is divided into RAM and ROM

DATA STORAGE MEDIA

A computer processes and stores data and instructions in the form of

two digits-0 and 1. These are called binary digits. These bits are

combined into larger units to hold greater range of values.

TYPES OF COMPUTER MEMORY

The computer memory can be classified into two categories-

PRIMARY MEMORY AND SECONDARY MEMORY.

1. PRIMARY MEMORY- It is also known as main memory. It is

in-built memory that is inside the CPU. It is subdivided into-

a) RAM (Random access memory)-Refers to read and write

memory. It is volatile in nature. It is small in size.

b) ROM (Read only memory)- It keeps the data permanently. It

is non volatile in nature that means even when a computer is

switched off, its data does not get lost.There are three different

kinds of ROM-

PROM (PROGRAMMABLE READ ONLY MEMORY)

EPROM (ERASABLE PROGRAMMABLE READ ONLY MEMORY)

EEPROM (ELECTRICALLY ERASABLE PROGRAMMABLE READ

ONLY MEMORY)

2. SECONDARY MEMORY- Secondary memory is used to store

information for a longer period. As internal storage is insufficient to

store large amount of data, secondary memory is required. Some of

the secondary memory are-

1. Hard Disk-It is fixed inside the cabinet of the CPU. The normal

storage capacity is 500gigabytes.

2. CD-ROM(Compact Disc Read Only Memory)-Commonly known as

CD. It can store 600MB to 750MB data on it.

3.DVD- It stands for Digital Versatile Disk. It is an optical disk storage

device. Its capacity range from 4.7GB to 8.5GB.

4.Pen Drive-It is the small data storage device that can be attached

outside a computer at a place called USB port. It is the most

convenient device to carry data.

5.Blue-ray Disc- It is similar to CD or a DVD in appearance but it can

hold upto 25GB of data.
