Count how many of the numbers are odd. If an odd number of them are odd, then their sum is odd. If an even number of them are odd, then their sum is even.

How would you determine whether the product of many natural numbers is even or odd?

If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.

Can you tell if the product of several numbers will be even or odd?

Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.


How could you determine whether a sum of numbers such as 127 plus 38 is even or odd?

The parity rules are: Odd + Odd = Even Even + Even = Even Odd + Even = Odd Even + Odd = Odd So the parity where one number is even is that of the other number. This means that you can go through a list of numbers and ignore all the even numbers. Every PAIR of odd numbers has even parity and by the previous paragraph, even parity can be ignored. So you can pair off odd numbers and ignore them.

How can you determine if a number is odd or even when the whole number has a decimal with it?

You can't. Only whole numbers are odd or even.

It doesn't matter what the first number is. All that matters is the ones place to determine if the number is odd or even.

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.

Can you tell if sum of several numbers will be even or odd?

Yes, all you have to do is to count the number of ODD numbers in the list. If it is odd, then the sum will be odd; if even, so will the sum. Knowing this can help you run a quick validity check when you sum up a list of numbers. (The method works because: a) the sum of two even numbers is even, and b) the sum pf two odd numbers is even, but c) the sum of an even number and an odd number is odd. Hence, if you only determine whether there are any unpaired odd numbers, you know the answer.)

Add them up and divide the sum by 2.
