"IT IS ALWAYS A ODD"
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
an odd numberSubtracting an odd number from an even number will always result in an odd number.
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.
The sum of an odd number and an even number is an odd number.
21 is an odd composite number
It is odd.
an odd number
21+9=20
In mathematics, an even number is an integer that is divisible by 2 without leaving a remainder. In the case of 21, when divided by 2, there is a remainder of 1, indicating that it is not evenly divisible by 2. Therefore, 21 is classified as an odd number.
It is odd.
5+5+5+5+1 That is only 5 numbers being added. There can be no answer for six numbers for the following reasons: The numbers are all odd. Two odd numbers make an even number. Two even numbers make an even number. 21 is odd. Take 6 odd numbers and add them up in pairs. Each pair of odd numbers gives an even number so there are 3 even numbers. Even + Even + Even = Even. So sum of any six odd numbers is even but 21 is not even.
odd * odd = odd answer even * even = even answer odd * even = even answer
"IT IS ALWAYS A ODD"
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
Odd
21 is the composite number because it's an odd number. 2 cannot be a composite number because it's even.
