Proof:
The biggest five digit even number is 99998. It is even because it is divisible by 2. It is the biggest because the next number 99999 is odd and the number after that is 100000 which is of six digits.
Now the smallest five digit odd number is -99999. The one smaller than this is a six digit number and the one larger than this -99997 is not an odd number.
Differences Between 99998 and -99999:
1.The last digit of 99998 is 8 and it is even because it is divisible by 2. But the last digit of -99999 is 9 and it is odd because it is divisible by 3.
2)8 is not a perfect square. It's square root is the fraction 2.828427…. But last digit 9 of the smallest one is a perfect square being equal to 3^2.
3)The numerical difference between the biggest five digit even number and the smallest five digit odd number is a positive or a negative number depending on how you take the difference.
99998 - (-99999) = 99998 + 99999 = (100000–2) + (100000–1) = 200000 -3
= 199997 (positive)
The difference calculated in the other way round, that is smallest - biggest
= -99999 - 99998 = -199997
