Square Trick
Squares of Numbers having 5 in the Units Place
This trick makes it easy to find the squares of numbers with digit 5 in the unit place.
Just like 25 x 25
to solving this question we use simple trick like this
25
x 25
625
in that u first write 25 at their tens place and for hundred place u only need to multiple 2 with its consecutive number.
in this firstly we need to multiply everyone just like 3 x 6 x 2 and than square the numbers like (3)2 , (6) 2 and than add the number with 36 always remember that leave unit place as it is. u should add with tens place not with unit place.
Other Examples are
(72) 2 = 5184 (first step 7 x 2 x 2 = 28, now squaring of the number 7 and 2 are 4904, add it with 28 while adding write unit number 4 as it is.)
(98) 2 = 9604 (first step 9 x 8 x 2 = 144, now squaring of the number 9 and 8 are 8164, add it with 144 while adding write unit number 4 as it is)
This trick makes it easy to find the squares of numbers with digit 5 in the unit place.

in that u first write 25 at their tens place and for hundred place u only need to multiple 2 with its consecutive number.
so in (25)2 = 2 x 3 25 = 625
Other Examples are
(45) 2 = 4 x 5 25 = 2025 (here we only need to multiply 4 with its consecutive number and write 25 at their tens place)
(85) 2 = 8 x 9 25 = 7225 (here we only need to multiply 8 with its consecutive number and write 25 at their tens place )
(115) 2 = 11 x 12 25 = 13225 (here we only need to multiply 11 with its consecutive number and write 25 at their tens place)
Squares of 2 digit number
This trick makes it easy to find the squares of 2 digit numbers
Example (36) 2
This trick involves 3 steps like this
First Step :-
3 x 6 x 2 = 36 ( here we always multilpy the number with 2 because we squaring)
Second Step :-
(3)2 (6) 2
0936 (find sqaures of numbers)
Third Step :-
0936
+ 36
1296
Ans :- 1296Other Examples are
(45) 2 = 4 x 5 25 = 2025 (here we only need to multiply 4 with its consecutive number and write 25 at their tens place)
(85) 2 = 8 x 9 25 = 7225 (here we only need to multiply 8 with its consecutive number and write 25 at their tens place )
(115) 2 = 11 x 12 25 = 13225 (here we only need to multiply 11 with its consecutive number and write 25 at their tens place)

Example (52) 2
This trick involves 3 steps like this
First Step :-
5 x 2 x 2 = 20 ( here we always multilpy the number with 2 because we squaring)
Second Step :-
(5)2 (2) 2
2504 (find sqaures of numbers)
Third Step :-
