Multiplication

Mathematical Operation: Multiplication is explained.

(1) Multiplication is repeated addition of a number itself to a certain number of times.

Example:-

Find the value of

Solution:-

= 5 + 5 [5 will be added twice]

=10

But, this method is not easy in finding multiplication of large numbers.

Example:-

Find the value of

Solution:-

[6 will be added 9 times]

6 + 6 +6 +6 +6 +6+6 +6 +6 =54

To make calculations easy, we use multiplication tables.

For your convenience and learning, multiplication tables from 2 to 20 are given below:-

Table of 1 Table of 2 Table of 3 Table of 4 Table of 5 Table of 6 Table of 7 Table of 8 Table of 9 Table of 10

Table of 11 Table of 12 Table of 13 Table of 14 Table of 15 Table of 16 Table of 17 Table of 18 Table of 19 Table of 20

Use of multiplication table:-

Example:-

Find the value of 6 × 9

Solution:-

6 × 9

To multiply it, remember table of 6 and write its product as answer.

6 × 9 = 54

(2)Multiplicand is the number which shows how many times repeated addition of the value of other number (multiplier) will be done in the multiplication. In simple words, the number which will multiply with other number is called multiplicand.

In the above example 9 is multiplicand.

(3)The number that multiplies is called multiplier.

In the above example, 6 is multiplier.

(4) The result of multiplicand and multiplier is called product.

In the above example 54 is product.

(5)When a number multiply by 0, the product will be 0.

(6)When a number is multiplied by 10, 100, 1000 etc. the product is obtained by placing as many zeros to the right of the multiplicand as the number of zeroes in the multiplier.

Ex:-
