Answer 1

Answer:

1.) Minimum 4 because 1000 + 1000 = 2000 which is 4-digit number and maximum 5 because 9999+9999=19998 is 5-digit number . The minimum number of digits in a sum of any two - four digit numbers are 4 and the maximum numbers of digits in a sum of any two four digit numbers are 5.

2.) The smallest 5 digit number is 10000 . The largest is 99999 . 99999-10000=89999 but since you have a zero based count , add 1 in 89999 . 89999+1=90000 a different 5 digit number.
