The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The sum of two odd numbers or two even numbers is an even number. The sum of an odd number and an even number is an odd number.
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)
Every odd or even number is a rational number, and there are a lot more rational numbers besides those.
The concepts "even" and "odd" apply to whole numbers. They don't make sense for other classes of numbers, such as rational numbers, real numbers, complex numbers, etc.

Count the number of negative numbers. If this is an even number, the sign is + and if it is odd, the sign is -.

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.
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.
The sign of a rational number does not depend on whether it is odd or even.
The sum of two odd numbers is always even; the sum of three odd numbers is always odd; the sum of four odd numbers is always even; the sum of five odd numbers is always odd; etc
The product of two odd numbers is always odd.
