Answer 2

In this question, we are required to add the smallest eight-digit number and largest nine-digit number.

The smallest number is a number that is small in its series and the largest number is the number that is largest in the series.

The greatest n digit number is obtained by placing the n number of 9s. Similarly, the smallest n digital number is obtained by placing one as the leftmost digit and the other n-1 digits as 0

The smallest eight-digit number is 10000000

The largest nine-digit number is 999999999

Now we need to find the sum of the smallest eight-digit number and the largest nine-digit number.

10000000 +  999999999  = 199999999

So, the sum is 199999999.
