Square of numbers using vedic mathematics

We can find the Square of any number in just less than 5 sec 


Square of numbers ending with ones place digit as 5 (up-to 95)
  • add one to tens place number and multiply by tens digit / ones place square
152 = 1 x 2 / 5 x 5          =  2 / 25    = 225

452 = 4 x 5 / 5 x 5          =  20 / 25    = 2025 

552 = 5 x 6 / 5 x 5          =  30 / 25    = 3025

752 = 7 x 8 / 5 x 5          =  56 / 25    = 5625

952 = 9 x 10 / 5 x 5          =  90 / 25    = 9025


Square of any number  (up-to 99)
  • tens place square / tens x ones x 2 / ones square
232 = 22 / 2x3x2 /32   =  5 / 2(12)/ 9   = 5,2,9 =529

582 = 52 / 5x8x2 / 82  =  33 / 6(86)/ 46 (64)  = 33,6,4 =3364
  
482 = 42 / 4x8x2 / 82  =  23 / 0(70)/ 46 (64)  = 23,0,4 =2304

322 = 32 / 3x2x2 / 22   =  10  / 2(12)/ 4   = 10,2,4 = 1024

882 = 82 / 8x8x2 / 82  = 77 / 413   (134)/ 46 (64)   = 77,4,4 =7744

Square of three digit numbers 
  • first 2 digits square / first 2 digit x ones digit x 2 / ones digit square
1232 = 122 / 12 x 3 x 2 / 32   =  144 / 2(72)/ 9   = 151,2,9 =15129

4532 = 452 / 45 x 3 x 2 / 32   =  2052 / 027  (270)/ 9   = 2052,0,9 =205209

2252 = 222 / 22 x 5 x 2 / 52   =  506 / 222  (222)/ 52   = 506,2,5 = 50,625

5242 = 522 / 52 x 4 x 2 / 42   =  2745 / 741  (741)/ 61   = 274576 = 274576

3242 = 322 / 32 x 4 x 2 / 42   =  1049 / 725  (257)/ 61   = 1049,7,6 = 104976
