Division and Multiplication
What is Division?
The word division defines as the splitting of work or object in equal parts. Division operation is the opposite of multiplication operation. The symbol which is used for division operation is (/), (÷) and a line __. For example,9/3, 9 ÷ 3Here, 9 is the dividend and 3 is the divisor.
Now, let us take an example, there is 12 chocolate in the box and there are 6 friends. Now, how much chocolate each of them will get?
Therefore, one has to divide 12 chocolates with 6 friends. 12 ÷ 6è 2 chocolate.
6 12(2 = Quotient))
12
0 (Remainder)
Now, during the division process, there are several times when we are left with the remainder. For example: –
There are 16 chocolates and there are 5 friends. Now, one has to find out how many chocolates each of them will get?
Here, 16 is dividend and 5 is the divisor. Therefore, we get
16 ÷ 5 è3 and we get remainder 1.
5 16 (3)
15 01
(5 x 3 è15)
What is Multiplication?
In mathematics, the word multiplications meanto add a number to itself several times. The multiplication operation provides an increased value of a multiplied number. For example – 10 multiplied by 4.
- 10 x 10 x 10 x 10 èHere, 10 is multiplicand which is the number that is multiplied and 4 is the multiplier number.
One can perform multiplication operation with whole number, decimals and with fractions etc.For example: – Multiply of 5 with 31/2 = 5 + 5 + 5 + 2.5 (half of 5) è 17.5.
Quiz
- What is the repeated sum of 4 x 4?
- 4 + 4 + 4
- 4 + 4 + 4 + 4
- 4 + 4 + 4 + 4 + 4
- 4 + 4
Answer: – 4 + 4 + 4 + 4, is the correct answer because as the result of 4 x 4 è 16. Therefore,
4 + 4 + 4 è 12
4 + 4 + 4 + 4 è 16
4 + 4 + 4 + 4 + 4 è 20
4 + 4 è 8

- In a store there are 61 boxes of pencils are present and every box has 14 pencils. Calculate how many pencils are present in the store?
- 850
- 754
- 854
- 750
Answer: -854, is the correct answer because
Here, the total number of pencils boxes is 61.
No. of pencils in each box is 14.
Therefore, in order to find out total number of pencils in the boxes multiply 61 with 14 we get the required result.
61 x 14 è61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 + 61 è854
- Find out missing number?
153 x 35 = (150 + 3) x ( )
- 30 – 5
- 30 ÷ 5
- 30 x 5
- 30 + 5
Answer: – 30 + 5, is the correct answer because 153 x 35 = (150 + 3) x (30 + 5)
30 – 5 è30, 30 ÷ 5 è6, 30 x 5 è150 and 30 + 5 è35

Answer: – Quotient è 5 and Remainder è 7, is the correct answer because
8 47 (5 = quotient)
40
07(Remainder)
- What is the result of expression 5 ÷ 0?
- 5
- 0
- Cannot divide by 0
- 50
Answer: -Cannot divide by 0, is the correct answer because zero means there is no number so that number divided by zero is undefined.
