How many 2 digit whole numbers have no odd factor except 1?
The two-digit whole numbers that have no odd factors except 1 are the powers of 2, as these numbers are only divisible by 1 and themselves. The two-digit powers of 2 are 16, 32, 64, and 128. However, 128 is not a two-digit number, so we only consider 16, 32, and 64. Therefore, there are three two-digit whole numbers that meet the criteria: 16, 32, and 64.
What is the two digit odd number?

How can you determine whether a sum of numbers is even or odd with out building a tile model or computing the sum?
You can just add the last digit of each number. Whenever you get a two-digit number, you can discard all digits except the last one. Another alternative is to count how many odd numbers there are - once again, you only need to consider the last digit. If the number of odd numbers is even, the sum is even; otherwise it is odd. (You can ignore even numbers for this calculation.)
What is the greatest 2 digit odd number?
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.
Is the product of two odd numbers odd or even?

What is the product of two odd numbers?

How many numbers are equal to the sum of two odd one-didit numbers?
You didn't state whether the two odd numbers to be added must be different odd numbers or whether they can be the same odd number. So I'll do both cases. Case 1: They can be the same odd number: They are all even numbers starting with 1+1=2 and ending up with 9+9=18. So you can get these 9 even numbers: 2,4,6,8,10,12,14,16,18. Case 2: They must be different odd numbers: If you require that the two single-digit odd numbers be DIFFERENT odd numbers, then you can't get 2 or 18, so you can only get these 7 even numbers 4,6,8,10,12,14,16. So the answer is either 9 or 7, depoending on whether the two odd numbers you are adding can or can't be the same odd number.
