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.)
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.
All even numbers are divisible by 2 with no remainder. Why are the numbers 1.3499,2.4596,4.4817 classed as even numbers? And 1.8221, 3.3201 are classified as odd numbers in numerical integration
There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.
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.
Just add the end numbers, so 3 + 5 + 4 + 7 = 19 which is odd. Alternatively, ignore even numbers [such as 4], and two odd numbers [3 and 5] added always make an even number [8], which leaves and odd number [7] so the answer will be odd. Example; five hundred different numbers, where 483 are even and 17 are odd, then no matter what the actual 500 numbers are the answer will be odd, as there is an odd [17] quantity of odd numbers.

If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
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.
you can tell cause odd numbers have something left over

There is no such pattern because there are no even odd numbers. Odd numbers, by definition, are odd and therefore, not even.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.

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.
