Galileo's law of odd numbers states that when adding or subtracting odd numbers, the result is always an odd number. This is because odd numbers can be represented as 2n + 1, where n is an integer. When two odd numbers are added or subtracted, the result will have (2n + 1) + (2m + 1) or (2n + 1) - (2m + 1) form, which simplifies to 2(n + m) + 2 or 2(n - m), respectively. In both cases, the result is still an odd number because it has a factor of 2 and an additional 1.

How do you explain what odd and even means?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
How many subsets with an odd number of elements does a set of 10 elements have - Can you explain?
512 subsets
Explain why 7654321 plus 5 is a composite number?
The first number is odd, the second is odd. Odd + Odd = Even ie the sum is even. Either number is greater than 2 so their sum is greater than 2. All even numbers greater than 2 are composite.
When you add an odd and even number together is the sum odd or even and why?
The best way I can explain this is the way my kindergardenn teacher taught me. In even numbers, all the numbers will have a partner. With 2 each little person/number will have a partner. Now with an odd number, (such as three) there will be a person/number alone. so if you add an even and an odd there will be on little person without a partner, causing it to be an odd.
Does composite numbers have an even number of factors correct or incorrect explain?
Incorrect. Square numbers are composite and have an odd number of factors.
Can you explain why some square numbers are odd numbers?
The square of any odd number is also an odd number for reasons that should be obvious.
Can a perfect square be a prime number Explain?
No. A prime number is always odd.
How do you explain what odd and even means?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
Will a negative number to the fifth power be a positive or a negative value explain?
Negative, because 5 is an odd number
How many subsets with an odd number of elements does a set of 10 elements have - Can you explain?
512 subsets
Julia says that prime numbers have to be odd and composite numbers have to be even. is she correct explain how you know?
Julia is incorrect. 2 is an even prime number and 9 is an odd composite number.

Does composite numbers have to be odd explain why?
The answer is 'no', so there isn't any 'why'. As a matter of fact, every EVEN number except 2 is composite, and every prime number bigger than 2 is odd..
Does composite numbers have an even number of factors correct or incorrect explain?
Incorrect. Square numbers are composite and have an odd number of factors.
the product of two even numbers is even and the product of odd numbers is odd explain with an example?
Any number, regardless of odd or even, if multiplied by an even number, is always even. Ex: 4x6 is 24 4x5 is 20 5x5 is 25
Can you explain why 10 has an even number of factors but 16 has an odd number of factors?
Because 16 is a square number and you wouldn't list the 4 twice.
