Why if you multiply odd number with another number the result is always odd number?
Well, the question is why. The first number is "even" + 1. Multiply both of these by your odd number. Now the "even" times "odd" is even, because every "1" in the odd number becomes a "2". And then the remaining 1 times "odd" must be odd, which is an even +1. Add it all up and you get evens everywhere except that final "1". So the result is even + 1 which is odd. There is a quicker way if you know how to multiply bracketed terms: odd x odd = (even + 1)x(even +1)= even x even +even +even +1 = must be odd. ========================== You've just read a truly impressive answer to a question slightly different from the one that was asked. The part of the question that comes after "Why if ..." is a false statement. If you multiply odd number with another number, the result is odd number ONLY if the nother number is also odd number.
What combination of numbers always results in an odd number?
Multiply two odd numbers Add an even and an odd Subtract an odd and an even
Why even number squared will be even?
because that's the theory of maths even x even = even even x odd = odd even + even = even even + odd = odd
When you multiply an odd number with an even will the product be even?
Yep
What happens when you multiply an odd number with an even number?
You get an even number as your answer.
What happens if you multiply odd by even?
If you multiply an odd number by an even number, the product (answer) will be even. Example: 5 x 4 = 20
What is the result of product of even numbers and odd numbers?
If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
What do you get when you multiply an odd number by two even numbers?
An even number. For example: 3 (odd) x 2 (even) x 6 (even) = 36 (even) Second example: 5 (odd) x 8 (even) x 2 (even) = 80 (even)
Why when you multiply an odd number with another odd number the result is a odd number?
yes, the product of 2 odd numbers is always an odd number. Well, the question is why. The first number is "even" + 1. Multiply both of these by your odd number. Now the "even" times "odd" is even, because every "1" in the odd number becomes a "2". And then the remaining 1 times "odd" must be odd, which is an even +1.

What combination of numbers always results in an odd number?
Multiply two odd numbers Add an even and an odd Subtract an odd and an even
Is the product of 5 and any number always odd?
No. If the number by which you multiply 5 is even, the product will always end in "0" and will be even:5 x 2 = 105 x 8 = 405 x 18 = 90If the number by which you multiply 5 is odd, the product will always end in "5" and will be odd:5 x 3 = 155 x 9 = 455 x 31 = 155
When you multiply two prime numbers you always get an odd number?
For 'odd' prime numbers this is true, but '2' is also a prime number , so you will have an even answer. Remember when multiplying even X even = even even X odd = even odd X even = even odd x odd = odd.
When you multiply 97 with 194 do you get an odd or even number?
Odd times even is even.
Are the multiples of an odd number always odd?
No, only every other multiple is odd. Example: 3,6,9,12,15,18
Why even number squared will be even?
because that's the theory of maths even x even = even even x odd = odd even + even = even even + odd = odd
Why are all multiples of 3 odd and even?
The multiples of all odd numbers are odd and even. Odd x odd = odd. Odd x even = even. Since odd and even numbers alternate, the multiples will alternate as well.
