Best Answer

Sum of two odd numbers is always an even number.

e.g. 1 + 7 = 8

Explanation:

The successor of an odd number is an even number and the successor is obtained by adding 1.

Let us assume any odd number, say n.

On adding 1(i.e. an odd number) to n we get an even number and again on addition of 1 or addition of 2(an even number) to n we get an odd number. If we continue to add like this we get to know that addition of two odd numbers is always an even number.

The sum of two odd numbers is always even.

The sum of the first six odd numbers is 36.

That isn't possible. The sum of three odd numbers will always be odd. You can make the sum of 3 prime numbers equal to 32 if one of them is 2 (which is not odd).

Some odd numbers can be written as the sum of prime numbers. 2 + 3 = 5

The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.

It is true that the sum of 2 even numbers is never odd

The sum of two odd numbers is always even.

The sum of the first six odd numbers is 36.

False. The sum of 3 and 3 is 6. And 6 is even. The product of two odd numbers is always odd. false the sum of 2 odd numbers is always even 3+3=6 5+5=10 103+103=206

No

The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.

Two odd numbers are always even

This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)

This depends on what "x" is. The sum of the first x odd numbers is equal to x^2 or x*x.
