    Hi Faisal,

    Doing multiple additions is the same. Except instead of adding 2 digits in one step, you add the digit of all numbers. It is just as easy to do.

    So in the first step you add the first digit of all numbers i.e. 1 + 6 + 2 + 4 + 2 + 2 = 17

    2354
    4563
    2342
    +2313
    17

    Next step you add the second digit of the all the numbers i.e. 4 + 5 + 3 + 5 + 3 + 3 = 23

    1457
    6532
    2354
    4563
    2342
    +2313
    17
    +23

    Combining the result from the previous two steps (17 & 23) we get 193.

    4563
    2342
    +2313
    193

    Next step 5 + 3 + 5 + 6 + 4 + 1 = 24

    1457
    6532
    2354
    4563
    2342
    +2313
    193
    +24

    Combining the result from the previous two steps (193 & 24) we get 1954.

    1457
    6532
    2354
    4563
    2342
    +2313
    1954

    Next Step 7 + 2 + 4 + 3 + 2 + 3 = 21

    1457
    6532
    2354
    4563
    2342
    +2313
    1954
    +21

    Combining the result from the previous two steps (1954 & 21) we get 193561.

    1457
    6532
    2354
    4563
    2342
    +2313
    19561

    You have the final answer 19,561
