Every odd number. Multiplying two even numbers gives an even number. Multiplying an odd and an even number gives an even number. Multiplying two odd numbers gives an odd number.

odd * odd = odd answer even * even = even answer odd * even = even answer

Yes

Your question is incomplete. Adding an even number with an odd number will always result in an odd number. Multiplying an even number with an odd number will always result in an even number.

Yes - while multiplying odd numbers by even numbers will always produce an even result.

You can tell it will be even when the number you are multiplying has a 2 4 6 8. You can tell it will be odd when the number you are multiplying has a 1 3 5 7.

The multiples of ODD numbers by ODD numbers are ODD. (e.g. 1 x 3, 3 x 3, 5 x 3) Multiplying any number by an EVEN number produces an EVEN number.

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Even minus odd is odd.

You can use the rule that says:* If the last digit is even, the entire number is even. * Similarly, if the last digit is odd, the entire number is odd.

Multiplying two odds together gives an odd result Otherwise multiplying one even and one odd, or two even numbers together gives an even result.

Because multiplying three by an even number will get an even product.

If there is an even number of minus signs, the answer is positive; if there is an odd number of minus signs, the answer is negative.

We can do so in two ways: Adding or subtracting an odd number by 61915. Multiplying 61915 by an even number.

It can be any polynomial rule with integer coefficients in which there are an even number of odd coefficients.

A maths rule is every odd becomes an even next number, but you probably knew that.

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.

"IT IS ALWAYS A ODD"

Odd

No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even

The sum of an odd and an even number is odd. Any odd number can be expressed as 2n + 1 (for some integer "n"). Any even number can be expressed as 2m (for another integer, "m"). The sum of the two is 2(m+n) + 1. Since the expression in parentheses is an integer, multiplying it by 2 gives you an even number. Adding 1 makes the entire expression odd.

No odd number has an even factor.

The difference of an odd number and an even number is an odd number.

An even number can be a multiple of an odd number OR an even number. An odd number cannot be a multiple of an even number.

All odd numbers are of the form 2n + 1, where n is an integer.So an odd number minus an odd number is (2n+1) - (2m+1) = 2n -2m = 2(n-m). Both n and m are integers, so while we don't know whether n-m is odd or even, we definitely know that it's an integer and that multiplying it by two cannot possibly give an odd number. So an odd number minus an odd number is an even number. For similar reasons, an odd number plus an odd number is also an even number.
