When does an even number of odd numbers equal an odd number?
Never. When you dont add the same odd number and even number of times. For example: 5 + 3 (2 odd numbers; and even amount of odd numbers ) = 8 5 + 3 + 7 = 15 an odd amount of odd numbers 5 + 3 + 7 + 9 = 24 another even amount of odd numbers. But never if you use the only same number
Why is and odd number minus an even number odd?
Because the second number from an odd number is odd, and every other number is an odd number. In fact, if you add or subtract an even number with any number, the result keeps the same parity as the other number. So an odd number minus an even number is odd, while an even number minus and even number is even.
When you halve an even number is the answer always odd?
No. For example, the even number 8.
Is 27 odd and even?
No. In fact, no number can be both odd and even at the same time.
When you divide and even number by 2 is the answer ever odd?
Yes for example 26/2 = 13 which is an odd number
