Is a odd number times a even number a odd number?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Odd times even is even.
When multiplying an odd number by an odd number why is the result odd?
The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
Why is odd times odd numbers always odd numbers?
In the same way that and odd plus and even is always odd. For example, 7*3 = (7+7) odd + odd = even , then add +7, apply rule that odd + even = odd and get that it equals 21.
Is the sum of an odd number and an even number always even?
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
When you multiply two prime numbers you always get an odd number?
No. 2 times 3 is 6. Multiplying any number by 2 will make it even. Other than that, since all other prime numbers are odd, yes.No, because 2 is a prime number, and any prime number multiplied by 2 is even. However, for any product in which 2 is not a factor, it is odd by definition.
