Answer 1) Because, odds with evens would be odd, so odds+odds=evens.
Answer 2) Relating this to an example, if you want to add 5 + 7, you could take 1 off each of these odd numbers, making them even. Your equation will now be 4 + 6, but you also have to add 2 to you answer because of that's the amount you took off to make the numbers even. You equation will now be 4 + 6 + 2, which is 12. Sorry if this is confusing....
None. Any two odd numbers add up to an even number.

No. No matter what you use, the sum of an odd number and an even number will always be odd.
Two odd numbers always sum to an even number. Always. Two even numbers always sum to an even number, and an odd number and an even number always sum to an odd number.
No 5 odd numbers add up to 100. The sum of any two odd numbers is even. The sum of any two even numbers is even. So the sum of any 4 odd numbers must be even. Take that and add an odd number and the sum must be odd. Therefore, the sum of any 5 odd numbers must be odd. 100 is even. In conclusion: The sum of any odd number of odd numbers is odd.
An odd number of odd numbers can not add up to an even number. There fore any 9 (odd) odd numbers can not add up to 50 (even).
There is no answer. Two odd numbers add up to an even number, and adding an odd number to an even number produces an odd number. Therefore three odd numbers cannot add up to an even number.
Multiply two odd numbers Add an even and an odd Subtract an odd and an even
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
None. Any two odd numbers add up to an even number.

Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
No. No matter what you use, the sum of an odd number and an even number will always be odd.
Two odd numbers always sum to an even number. Always. Two even numbers always sum to an even number, and an odd number and an even number always sum to an odd number.

Unless this is a trick question, none of them do. Zero is an even number, so therefore no positive odd number and negative equivalent will add to form an odd number. Similarly, negative odd numbers will add to form negative even numbers, and positive odd numbers will add to equal positive even numbers.
