Using the method of Vedic Maths we can easily get square of any number that is close to 50 in just few seconds with oral calculation. This is very useful in competitive exams:

Vedic Maths - square of any number

Lets try for the number 46

Let the Number be X = 46 

Find the Difference between X and 50 (As a base Number) 
so we Get,   

50 - 46 = 4    --------- ( Lets it A)

Now, We go Through 2 Fast Steps i.e; 

Step 1 – If the original number (X) is greater then 50 then Add the number 25 to (A) , Else if the  original number (X) is smaller then 50 then subtract the number 25 to (A)

In this case our (X) i.e. 46 is smaller then 50  so we substract
Subtract Difference With 25 i.e; 

25 - 4 = 21  ---------- (Lets call it B )

Step 2 – Square the (A)

4²= 16       --------- (Lets call it C)

Now just Write (B) and (C) Next to each other – 2116 Which is our Answer

 

Lets try for the number 57

Let the Number be X = 57

Find the Difference between X and 50 (As a base Number) 
so we Get,   

57 - 50 = 7    --------- ( Lets it A)

Now, We go Through 2 Fast Steps i.e; 

Step 1 – If the original number (X) is greater then 50 then Add the number 25 to (A) , Else if the  original number (X) is smaller then 50 then subtract the number 25 to (A)

In this case our (X) i.e. 57 is bigger then 50  so we Add
Adding (A) With 25 i.e; 

25 + 7 = 32  ---------- (Lets call it B )

Step 2 – Square the (A)

7²= 49       --------- (Lets call it C)

Now just Write (B) and (C) Next to each other – 3249 Which is our Answer
