Yes - while multiplying odd numbers by even numbers will always produce an even result.
No. Two odd numbers added together always give an even number. Two even numbers added together always give an even number. An odd and an even number added together always give an odd number. So, if we have 5 odd numbers - a, b, c, d and e a + b will be even c + d will be even So if (a + b) + (c + d) is even, adding e to that will have to be an odd number - but 50 is even, so it cannot be done.
That's impossible. Adding up an odd number of odd numbers will give an answer that is an odd number. 50 is an even number. So adding up 5(5 is an odd number) odd numbers will not give 50, an even number.
55
Odd
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.
Yes
Your answer will always be even
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.
No, only every other multiple is odd. Example: 3,6,9,12,15,18
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.
That happens because 5 is an odd number. An odd number times an odd number will give you an odd product; an odd number times an even number will give you an even product. The same happens for the multiples of any other 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.
The sum of an odd number and an even number is an odd number.
Multiplying two odds together gives an odd result Otherwise multiplying one even and one odd, or two even numbers together gives an even result.
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.
