Two odd numbers added together will always be an even number. I'll show how:
Let M and N be any two integers. 2M is even, and 2N is even.
So (2M +1) is an odd number, and (2N + 1) is an odd number.
(2M +1) + (2N +1) = 2M + 1 + 2N +1 = 2M + 2N + 2 = 2(M + N + 1), which is even.

There are no 5 odd numbers that when added together make 30.Two odd numbers added together make an even numberAn odd number plus and even number makes an odd number.From the five odd numbers:Take two of them and add them together getting an even number and four odd numbersAdd another of the odd numbers to this even number and you will have three odd numbersAdd two of these together and you will have one even and one odd number.Finally add these odd and even numbers together and the result will be an odd numberBut 30 is an even number, so cannot be the sum of five (or any odd number of) odd numbers.
Multiplying two odds together gives an odd result Otherwise multiplying one even and one odd, or two even numbers together gives an even result.
It is impossible.
The answer depends on how many odd numbers are being added together: even numbers make no difference.If the count of odd numbers is odd then the total is odd, andff the count of odd numbers is even then the total is even.
