SQUARE:
Find the square of two digit number:
(BA):
Eg:
(29) Here 2 is B and 9 is A
1-remainder
A^2 9^2= 081
A*B*2 9*2*2= 036 (+) [ A^2 +A*B*2 B^2]
B^2 2^2= 04
----------------------------------------------------
0841
----------------
Find the square of three digit number:
(CBA):
Eg:
(193) Here 1 -C, 9-B, 3-A
A^2 3^2= 1 09
A*B*2 3*9*2= 1054 (+)
B^2+(A*C)*2 9^2+(3*1)*2= 087
(B*C)*2 (9*1)*2= 018
C^2 1^2 01
