Prove that the sum of two odd numbers is odd
The sum of two odd numbers is odd because an odd number plus an odd number is an even number plus an odd number, which is still an odd number.
To prove this, we can use the definition of odd and even numbers. An odd number is an integer that is not divisible by 2, and an even number is an integer that is divisible by 2.
Now, let's consider the sum of two odd numbers, a and b. We can write this as:
a + b = c
where c is the sum of a and b.
Since a and b are both odd numbers, they are not divisible by 2. This means that the sum of a and b, c, is also not divisible by 2. In other words, c is an odd number.
Therefore, the sum of two odd numbers is always an odd number. This completes the proof.
