Why is it hard to calculate 99 plus 99?

Answer 1

It is NOT hard, I can do that sum in my head.

99

99

Take the right had column 9+9 = 18

remember the 8 and carry the ONE in you head

Take the left had column 9+9 = 18 .

to the 18 add the ONE you were carrying in your head to make 19 and write it down, followed by the 8 you remembered.

99+99 = 198

A:It's not that hard! 100 + 100 = 200. Take away 2. Answer. 198.
