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

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

2354
4563
2342
+2313
17
+23

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

193

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

193
+24

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

Next Step 7 + 2 + 4 + 3 + 2 + 3 = 21

+2313
1954
+21

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

19561

You have the final answer 19,561
