Question

Find the sum and the difference between the largest 4 -digit number and the smallest 5 -digit number.

Answer 1

Step 1: Largest 4 -digit number = 9999

Step 2: Smallest 5 -digit number = 10000

Step 3: sum of the largest 4 -digit number and the smallest 5 -digit number = 10000 + 9999 = 19999

Step 4 : Difference between largest 4 -digit number and the smallest 5 -digit number = 10000 – 9999 = 1

Hence, sum of the largest 4 -digit number and the smallest 5 -digit number = 10000 + 9999 = 19999

Difference between largest 4 -digit number and the smallest 5 -digit number = 10000 – 9999 = 1
