If you need to add 2 large numbers, it may become complex and time consuming. Specifically for candidates who are preparing for competitive exams as they can not afford to waste even a second extra.

I have a very simple and ultra quick method to solve complex addition problems in a fraction of moment. This method is ultra fast because all temporary/intermediate calculation can be done in mind i.e. without pen & paper.

In mental addition method

  • add a number in first addend to make it multiple of 10 or 100.
  • substract same number from second addend to balance.
  • add new addends in mind.

Ex-1 .

  359
 +462

Quickly you can identify that first addend will become multiple of 10 by adding 1. Thus given question can be transformed to as below.

  360
 +461

Now start addition from Left side

300 + 400 = 700,
60+ 61 = 121
=> 700+121 = 821.

Above mentioned temporary/intermediate steps will be performed in mind.

With little practice, you will become master of this method to solve complex addition problems in a fraction of time.

Now, it’s practice time for you.
