Multiply two odd numbers Add an even and an odd Subtract an odd and an even
An odd number of odd numbers can not add up to an even number. There fore any 9 (odd) odd numbers can not add up to 50 (even).
Yes. Even + Even = Even, Odd + Odd = Even and Even + Odd or Odd + Even = Odd
Odd numbers are always higher than even numbers . And even numbers are easier to add than odd numbers for some people .
Always. even + even = even odd + odd = even even + odd = odd odd + even = odd To summarise, if you add like numbers you get even, otherwise you get odd.
None. Any two odd numbers add up to an even number.
There is no answer. Two odd numbers add up to an even number, and adding an odd number to an even number produces an odd number. Therefore three odd numbers cannot add up to an even number.
no, it can't be. that's because only an even and even numbers or odd and odd numbers add up to be even. so no it cannot be even.
No three odd numbers can add up to an even number.
No 5 odd numbers add up to 100. The sum of any two odd numbers is even. The sum of any two even numbers is even. So the sum of any 4 odd numbers must be even. Take that and add an odd number and the sum must be odd. Therefore, the sum of any 5 odd numbers must be odd. 100 is even. In conclusion: The sum of any odd number of odd numbers is odd.
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.
You must add either two odd numbers or two even numbers.
Unless this is a trick question, none of them do. Zero is an even number, so therefore no positive odd number and negative equivalent will add to form an odd number. Similarly, negative odd numbers will add to form negative even numbers, and positive odd numbers will add to equal positive even numbers. Somebody please inform me if I'm missing something simple here.
No. An odd plus an odd is even, and an even plus an odd is odd. Thus, you will always end up with an odd number if you add only three odd numbers together, and 50 is even.
The answer depends on how many odd numbers are being added together: even numbers make no difference.If the count of odd numbers is odd then the total is odd, andff the count of odd numbers is even then the total is even.
No. No matter what you use, the sum of an odd number and an even number will always be odd.
because it can, if you add odd numbers the always don't have to be an odd number
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.
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
