This method is convenient for finding squares of two digit numbers only.As the number of digits increases ,this method becomes difficult and time-consuming.This method uses the identity for finding the square of a two digit number ab (where a is the tens digit and b is the units digit).
We follow the following steps to find the square of a two digit number ab (where a is the tens digit and b is the units digit).
Step I: Make three columns and write the value of respectively in these columns as follows :
As an illustration let us take ab = 57.
.
Column I | Column II | Column III |
25 | 70 | 49 |
Step II : Underline the units digit of ( in column III ) and add its ten digit,if any,to ( in column II )
Column I |
Column II |
Column III |
25 |
70 +4 |
|
74 |
Step III : Underline the unit digits in column II and add the number formed by tens and other digit , if any , to in column I.
Column I |
Column II |
Column III |
25 +7 |
70 +4 |
|
32 |
Step IV: Underline the number in column I
Column I |
Column II |
Column III |
25 +7 |
70 +4 |
|
32 | 4 | 9 |
Step V: Write the underlined digits at the bottom of each column to obtain the square of the given number.
In this case ,we have
