What is the result of product of even numbers and odd numbers?
Even x even = even
Odd x odd = odd
Even x odd = even
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.
If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.
Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product. If all of the numbers being multiplied together are odd, the product will be… Read More
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.
Any two odd numbers will have an odd product and an even sum.
No such numbers exist; the product of two odd numbers is always odd.
The product of two odd numbers is never even.
How would you describe the rule for determining whether the product of many natural numbers is even or odd?
I would describe the rule as one of the simplest possible. The product is odd only if each of the natural numbers is odd. If any one of them is even, the product is even. I would describe the rule as one of the simplest possible. The product is odd only if each of the natural numbers is odd. If any one of them is even, the product is even. I would describe the rule… Read More
Without knowing what the product is, it will be difficult to help. Presumably, you can tell the difference between even and odd numbers. If you are trying to predict, the product of two evens is even, the product of two odds is odd and the product of an even and an odd is even.
No - adding an odd quantity of odd numbers will always result in an odd number.
Any pair of one even and one odd number will have an even product and an odd sum.
Multiplying two odds together gives an odd result Otherwise multiplying one even and one odd, or two even numbers together gives an even result.
I guess you mean "product" - the product of two odd numbers is odd. (For example, 3x3=9, 5x3=15, etc.
Yes - while multiplying odd numbers by even numbers will always produce an even result.
There are 3 cases: An even number time an even number such as 2*6=12 is always even. Proof: Since even numbers can be expressed as 2*X and 2*Y, their product is 4xy which is even. An even number times an odd number (same as odd times even) such as 2*3=6 is always even. Proof: 2X represents an even number and 2Y+1 represents an odd number. Their product is 4XY+2X=2(2XY+X), which is even. An odd number… Read More
None. The sum or product of any two even numbers must be even.
If you're adding an odd number of numbers, if two are even and one is odd, you will get an odd number as a result. Three odds are odd. If two are odd and one is even, you have an even result. Three evens are even.
No two consecutive numbers have a product that is an even number. Any two consecutive numbers include one odd number and one even number. The product of one odd number and one even number is always an odd number.
This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)
No, the product will always be even.
Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.
The sum of three odd numbers is odd but 270 is even, therefore there are no three odd numbers that add to 270. Similarly the product of two of more odd numbers is odd but 270 is even, therefore there are no three odd numbers that multiply together to get 270.
No. Double any odd number. The result is even.
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number… Read More
Sum is always even, product is always odd.
You will have a long search on your hands because 5 odd numbers will never make 30. Any two odd numbers added together will result in an even number. Any two even numbers also result in an even number. An even and an odd number will always rsult in an odd number, so taking 5 separate odd numbers... odd1 + odd2 = even1 odd3 + odd4 = even2 even1 + even2 = even3 so, after… Read More
No. It only means they weren't both odd (or another way, that at least one of them was even). An example would be 8 x 9 = 72; the product is even, yet one of the numbers was odd.
There is no set of odd numbers whose product is 56 since the latter is even.
The result is an odd number.
You need an odd and an even to get an odd. 2 odds can make and odd or an even. Simply, it's just a pattern.
Let E1 and E2 be two even numbers. Then (E1+1)(E2+1) will be the product of two odd numbers. We have E1*E2 +E2+E1+1. Now when we add or multiply even numbers, we get even numbers and we add 1, it's odd.
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. Add it all up and you get evens everywhere except that… Read More
There are no 5 odd numbers that when added together make 30. Two odd numbers added together make an even number An odd number plus and even number makes an odd number. From the five odd numbers: Take two of them and add them together getting an even number and four odd numbers Add another of the odd numbers to this even number and you will have three odd numbers Add two of these together… Read More
The product (result of multiplication) is always odd. For example: 3*3=9 5*5=25 7*7=49
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Odd times odd is always odd.
Since there are an odd number of negative numbers, the result will be negative.
I'm assuming you multiply the numbers rolled. Thus the rules of even and odd numbers come into play. The only way to get an odd product is to roll two odd numbers. The probability desired is 1 minus the probability of rolling two odd numbers. The odds of rolling an odd number is 1/2. Since the rolls are independent events, the odds of rolling two odd numbers is (1/2)2 = 1/4 So the probability of… Read More
There are never 3 even numbers that add up to an odd number because all of the numbers are even so the result/sum will have to be an even number.
No. 9 X 2 = 18 One is even and one is odd.
It is the same as determining the sign of the product of two integers; + x + = + + x - = - - x + = - - x - = + OR If only positive numbers are multiplied, the result is positive. If positive and an even number of negative numbers (for example, + x - x -) are multiplied, the result is positive. If positive and an odd number of negative… Read More
The product of two odd numbers is always an odd number.
Let me show this to you by an example : Suppose we wish to multiply 3 and 7. Product or Multiplication by any device is actually carried by the process of addition of 3 seven times, i.e. 3+3+3+3+3+3+3 = 21. Because the two numbers are odd, the result is always odd. To Summarize, addition of an odd number(i.e. 3) to itself an odd number of times(i.e. 7) always results in an odd number. The product… Read More
When multiplied together, an odd number and an even number will always produce an odd number. Two consecutive numbers consist of one odd number and one even number, so their product is always an odd number. N-n-n-no! Any number multiplied by an even number yields an even product. Ever;y even number can be expressed as 2*M for some M. If we multiply 2*M by Y, the product is 2*M*Y = 2*(M*Y) which is even. So… Read More
As there are two consecutive integers then one must be an even number and the other an odd number. If the numbers are y and y + 1 then if y is even, y + 1 is odd and if y is odd then y + 1 is even. The product of an even integer and an odd integer is always even. The question therefore has no answer. 121 = 112 but this is not… Read More
If you want to get an odd number as a result: * Add any even number with any odd number. * You can also add any three odd numbers, or two even number and an odd number.
When you add them, you always get an even number; when you multiply them, the result is always odd.
Let's take a look at this. For any integer n, 2n always be even, then the next consecutive number 2n + 1 must be odd. Let add them first, 2n + 2n + 1 = 4n + 1 = 2(2n) + 1 So their sum is odd, since every even number multiplied by 2 is also even. Let's multiplied them, 2n(2n + 1) = (2n)^2 + 2n Their product is even, since every even number… Read More
Odd numbers do NOT have a factor of 2. When an Even number is divided by an Odd number with no remainder, the prime factors of the divisor cancel out the prime factors of the dividend, but there will be no prime 2 to cancel the prime factor of 2 in the dividend leaving the the quotient to have a factor of 2, and so will be Even. --------------------------------------------------------- Alternatively, consider what happens when you… Read More
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be even.
No all the numbers that are product of 2 and some other number are even numbers In this case 30 is a product of 2 and 15
Odd and even numbers are whole numbers (integers) such as 1,2,3 etc... If an integer is divisible by "2" without leaving a remainder (i.e. it will result in an integer) then it is even. If an integer will not result in another integer when divided by 2 then it is odd. Examples: 2 & 4 are even as: 2/2 = 1 and 4/2 = 2 (both results are whole numbers) 1 & 3 are odd… Read More
