1. Adding by breaking down : This is a very simple but extremely helpful trick for the bank po, bank clerk or other competitive exams with which you can add the two or more numbers mentally in quick time without using a pen.

 Example-1             
                             37 + 46


Step-1 we add the place values of  tens digits of both the numbers(highlighted in red)
                    
                            30 + 40 = 70
Step-2 Now, we add the unit digits of both the numbers separately(highlighted in blue)

                             7 + 6 = 13

Step - 3 Finally, we add the values we get at steps 1 and 2 together.

                            70 + 13 = 83
Example- 2
             
                            86 + 112
 
Step 1   We add 80 and 110
          
                           80 + 110 = 190

Step 2 we add the unit digits 6 (of 86) and 2 of (112)

                            6 + 2 = 8

Step 3 In final step we add the results of step 1 and step 2 (highlighted in red)

                             190 + 8 = 198
Example- 3
             
                            83 + 123 + 67
 
Step 1   We add 80 and 120 & 60
          
                           80 + 120 + 60 = 260

Step 2 we add the unit digits 3 (of 83), 3 of (123) and 7 (of 67)

                            3 + 3 + 7 = 13

Step 3 In final step we add the results of step 1 and step 2 (highlighted in red)
                            260 + 13 = 273

Believe me this is the very tricky method to calculate faster. Below we are providing a few practice sets for you. Each set has certain time limit. Take these Tests and Try to add mentally. Never use a pen/pencil.
