What are the 5 odd numbers whose sum is 30 from 1 to 13?
An odd number of odd numbers can't add up to an even number.
How do you tie 50 cows in 5 sticks by odd numbers?
It cannot be done. Five odd numbers add up to an odd number and so cannot equal 50.
What 9 odd numbers add up to 50?
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).
What 3 consecutive odd numbers equal 270?
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.
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.
