On the U.S. interstate system, even numbers indicate East/West routes; Odd numbers represent North/South routes; 3 number routes generally indicate belt-routes or local alternates.
No, odd numbered highways go North and South. Even numbered highways go East and West. Three digit highways are bypasses around cities.
The greatest two-digit odd number is 99. In a two-digit number, the first digit can range from 1 to 9, and the second digit can range from 0 to 9. Since we are looking for an odd number, the second digit must be odd, limiting our options to 1, 3, 5, 7, or 9. Among these, 99 is the greatest possible two-digit odd number.

Look at the last digit. If the last digit of a number is even, the whole number is even. If the last digit is odd, the number is odd.
To form a 4-digit odd number, the last digit must be one of the odd digits (1, 3, 5, 7, 9), giving us 5 choices. For the first three digits, we can use odd digits freely (repeating allowed), giving us 5 choices for the first digit and 5 choices for the second digit. The third digit must be an even digit (0, 2, 4, 6, 8), but cannot repeat; therefore, we have 5 choices for the first digit and 4 choices for the second digit. Thus, the total number of valid 4-digit odd numbers is calculated as (5 \times 5 \times 5 \times 5 = 625).
Look at the last digit. If the last digit is even, the number is even. If the last digit is odd, the number is odd.
It is 3823.
Look at the last digit. If a number's last digit is even, the number is even. If the last digit is odd, the number is odd.
No, my second to last phone number ended in 3836.
Which is the smallest nine digit odd number?
If the second digit is 1, 2, 3 or 4 replace it by 0. If the second digit is 6, 7, 8 or 9 replace it by 0 and increase the first digit by 1. If the second digit is 5, then, if the first digit is even, replace the second digit by 0, if the first digit is odd, replace the second digit by 0 and increase the first digit by 1. Many people will require that 5 as the second digit should be treated the same as 1-4. This ignores the upward bias introduced and IEEE 754 standard for rounding.
The largest odd four-digit number is 9999. It is odd because it ends with the digit 9, which is an odd number. Being a four-digit number, it falls within the range of 1000 to 9999.
