Dear Babu

It will help to sove mathematics question in faster way. e.g.   to get square of any number ending 5

  1. Take the first digit and multiply it by the next highest number.
  2. Put "25" after the above computation.

    • Example: Square 65.

Take the first digit (6) and multiply it by the next highest number (7).
6 x 7 = 42
Place 25 after the product above. 42[25} --> 4225

All the best.
