We know the process of multiplying 1-digit number by another 1-digit number. The multiplication of one-digit numbers is done with the help of the multiplication table of the number concerned.
Suppose, if we have to multiply 7 by 5, we put the numbers in column form.
7
× 5
35
We need to read mentally the multiplication tables of 7 to get 7 fives are 35.
This 35 is written as product. We say 7 multiplied by 5 is equal to 35.
Here, 7 is the multiplicand, 5 is multiplier and 35 is the multiple fact of product.
7 and 5 are also called factors of the product 35.
Examples
of multiplying one-digit numbers:
1. Multiply 6 by 3.
Solution:
First we need to arrange the numbers in column form.
6
× 3
18
We need to read mentally the multiplication tables of 6 to get 6 times three are 18.
This 18 is written as product. We read it as 6 multiplied by 3 is equal to 18.
Here, 6 is the multiplicand, 3 is multiplier and 18 is the multiple fact of product.
6 and 3 are also called factors of the product 18.
2. Multiply 9 by 6
Solution:
First we need to arrange the numbers in column form.
9
× 6
54
We need to read mentally the multiplication tables of 9 to get 9 times six are 54.
This 54 is written as product. We read it as 9 multiplied by 6 is equal to 54.
Here, 9 is the multiplicand, 6 is multiplier and 54 is the multiple fact of product.
9 and 6 are also called factors of the product 54.
3. Multiply 3 by 2.
We have learnt that 3 x 2 = 6.
Let us now learn how to write it using the vertical method.
Step I: Write the numbers according to place value.
Step II: Multiply the digits at the ones place.
So, the product of 3 and 2 is 6.
We write: 3 × 2=6
We read: Three twos equal six
Thus, to multiply one-digit number by another one-digit number its very important to know the multiplication tables of the concerned number to find the product of the numbers.
