  ### Simplest way to square a Number
  
  Suppose you want to Square a Number “AB i.e equal to AB^2 = AB * AB
  
  Simplest method to follow is Cris cross mothos: A^2/2AB/B^2
  Example 1) Suppose you want to square 24, i.e 24 x 24, so from the criss-cross method.
  = 2^2 / 2 (4 x 2) / 4^2
  = 4 / 16 / 16 (add carry 1 to 16)
  
  = 4/16+1/6
  
  =4+1/7/6
  
  =576
  
  Example 2) Square of 29 = ?
  Now a = 2 and b = 9, by the above observation we substitute the values.
  = 2^2 / 2 (2 x 9) / 9^2
  = 4 / 36 / 81 ( hear 8 is a carry, so add it to the preceding number )
  = 4 / 36 + 8 / 1 ( after adding 8 to 36 you get 44, carry 4 to the preceding number)
  = 4 / 44 / 1
  = 4 + 4 / 4 / 1
  = 8 / 4 / 1
  = 841

  useful method, thanks.

  Thank you.
  To square a number ending with 5.
  eg: 15
  multiplication of the first didgit and next no of it. and 25 (i.e 5^2)
  
  Square of 15 is: 1*2 25=2 25 =225
  eg: 35 => 3*4 25 => 12 25=> 1225
  Eg: 95=> 9*10 25 => 90 25=> 9025
  some times the usual methos is more better than the shortcuts.
