MULTIPLICATION WITH THE HELP OF TABLE –
Multiplication with the help of table will be performed by recall of number table as per requirement.
Example.1) Multiply 5 by 3
Ans.) Here the given calculation is - multiply 5 by 3
Here we can observe that there are two digit in the above given calculation is 5 & 3 respectively, so we have to recall the table either 5 or 3
Table of 5 Table of 3
5 X 1 = 5 3 X 1 = 3
5 X 2 = 10 3 X 2 = 6
5 X 3 = 15 3 X 3 = 9
5 X 4 = 20 3 X 4 = 12
5 X 5 = 25 3 X 5 = 15
5 X 6 = 30 3 X 6 = 18
5 X 7 = 35 3 X 7 = 21
5 X 8 = 40 3 X 8 = 24
5 X 9 = 45 3 X 9 = 27
5 X 10 = 50 3 X 10 = 10
From the above two number table of 5 & 3 we can find –
multiply 5 by 3 = 5 X 3 = 3 X 5 = 15
so, multiply 5 by 3 = 15 (Ans.)
Example.2) Multiply 8 by 6
Ans.) Here the given calculation is - multiply 8 by 6
Here we can observe that there are two digit in the above given calculation is 8 & 6 respectively, so we have to recall the table either 8 or 6.
Table of 8 Table of 6
8 X 1 = 8 6 X 1 = 6
8 X 2 = 16 6 X 2 = 12
8 X 3 = 24 6 X 3 = 18
8 X 4 = 32 6 X 4 = 24
8 X 5 = 40 6 X 5 = 30
8 X 6 = 48 6 X 6 = 36
8 X 7 = 56 6 X 7 = 42
8 X 8 = 64 6 X 8 = 48
8 X 9 = 72 6 X 9 = 54
8 X 10 = 80 6 X 10 = 60
From the above two number table of 8 & 6 we can find –
multiply 8 by 6 = 8 X 6 = 6 X 8 = 48
so, multiply 8 by 6 = 48 (Ans.)
Example.3) Multiply 9 by 10
Ans.) Here the given calculation is - multiply 9 by 10
Here we can observe that there are two digit in the above given calculation is 9 & 10 respectively, so we have to recall the table either 9 or 10.
Table of 9 Table of 10
9 X 1 = 9 10 X 1 = 10
9 X 2 = 18 10 X 2 = 20
9 X 3 = 27 10 X 3 = 30
9 X 4 = 36 10 X 4 = 40
9 X 5 = 45 10 X 5 = 50
9 X 6 = 54 10 X 6 = 60
9 X 7 = 63 10 X 7 = 70
9 X 8 = 72 10 X 8 = 80
9 X 9 = 81 10 X 9 = 90
9 X 10 = 90 10 X 10 = 100
From the above two number table of 9 & 10 we can find –
Multiply 9 by 10 = 9 X 10 = 10 X 9 = 90
so, multiply 9 by 10 = 90 (Ans.)
