greatest two digit number is 99. smallest whole number is 0 there fore 99-0=99
the answer is = first 2-digit number by using 48= 28,82 and in 3 digit is=282,228,822,822
No. When adding the smallest 2 digit number (= 10) to the smallest 2 digit number (again, 10) the result is a 2 digit number (10 + 10 = 20). When adding the largest 2 digit number (= 99) to the largest 2 digit number (again, 99) the result is a 3 digit number (99 + 99 = 198). As you can see, you'll either get a 2 or 3 digit number, but never a 4 digit number.
It would help to know which digit. 0 appears in 9 numbers and each of the others in 18 numbers.
