Single Digit Multiplication

Repetitive addition is called multiplication. Previously we have learned sing digit addition. Now ask-math will show you how addition is used in one digit multiplication.

 [• • • •]  joined with [ • • • • ] gives[• • • • • • • •]    4            +                   4          =             8 2 x 4 = 8

In the above example, there are two boxes and each box contains 4 dots so we multiply as
2 x 4 = 8

Example : Mac is getting four diamonds everyday. So how many diamonds he has in 5 days?

1st day = 4 ; 2nd day = 4 ; 3rd day = 4 ; 4th day = 4 and 5th day =4
Now count all the diamonds so you will get the total number of diamonds.
But easy way is just multiply number of diamonds and number of days.
[Number of diamonds ] x [ Number of Days] = [Total number of diamonds].
4 x 5 = 20
So total number of diamonds Mac has in 5 days are 20.
For one digit multiplication, you should know the multiplicative tables from 1 to 9.
To learn the table you can visit

Example :
2 x 8 = 16
3 x 2 = 6
7 x 2 = 21
9 x 3 = 27
4 x 9 = 36
7 x 1 = 7
9 x 0 = 0

Vertical multiplication:
Step 1 : Write the first number.
Step 2 : Put the multiplication sign below it on left side.
Step 3 : Write the other number beside it and below the first number.
Step 3 : Make a line below the number.
Step 4 : Write the answer below the line.

Some solved examples on vertical multiplication:

 4               8              7  x 2            x 4           x 3 ------    --------     --------    8              32           21
