13 is an odd number. Anything that cannot be evenly divided by 2 is an odd number. The number 13 also happens to be the sixth prime number which also makes it odd (strange in this case). The first few primes are 1, 3, 5, 7, 11, 13, 17, 23, 29, etc.
These number have the strange property of of not being divisible by any whole number except 1 and itself. This also means that every Prime number will also be odd.

If you subtract 13 from an even number the answer will be odd?
Correct.
If the sum of two numbers is even then the two numbers must be even?
If the sum of two numbers is even, the two numbers are either both even or both odd. A few examples:2 + 4 = 6 (even + even = even)2 + 3 = 5 (even + odd = odd)5 + 2 = 7 (odd + even = odd)7+13 = 20 (odd + odd = even)
What is an odd plus an even?
Well, lets say you add 3 and 6, you would get 9 which is odd. How about 7 and 6 is 13 again which is odd so I think the answer would be... Even + Odd = Odd :)
If you add 3 to an even number the sum would be odd or even?
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
How can you determine wether a sum of several numbers such as 13 45 24 17 is even or odd?
Go through each of the numbers, and count how many of them are odd. If you count an odd number of them, then their sum is odd. If you count an even number of them, then their sum is even.
