If we square 11, it is very simple put 1(2*1)(12)get 121 same as square 12 put 1(2*2)(22) get 144 again for 13 we get 169 and for 14 we get 1 8 16=196 and so on.
When we go deep, we find that there is symmetry of two types
(2,4,6,8,10,12 ,14,16,18,20 …. Diff is always 2) &
(1, 4 , 9 ,16,25,36,49,64,81,100 ) diff. is 3 5 7 9 11 13 15 17 19 and diff. of 3 5 7 9 11 always 2, so there is true symmetry .
Up to 19 it is right but at 20 how we can put 1 20 100 just because of symmetry.

There is a symmetry, from here I got a method, which is shown as below for 31, 41, 51 and so on.
