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.
You cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.
To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
If the factorization includes the number 2, it's even. If not, it's odd.
whenever you add an even number the answer will be the same (odd/even) as the other number

its easy to tell that if the last number ends with 0,2,4,6,8,10,12,14,16,18,20 so on and so on then its even if the answer starts with a 1,3,5,7,9,11,13,15,17,19 so on so on then its an odd number
To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.
It is a negative number. The answer is the same whether there is an odd or even number of addends.
No, you can tell by looking at the final number. If it is even, then the whole thing is even. If it's odd, then the whole thing is odd. The odd numbers are 1,3,5,7,9 the even numbers are 2,4,6,8 (if a number ends in 0 it is even, but 0 itself is debated over whether or not it's even)
it is odd if when you divide it by 2 you do not get a whole integer
you can tell cause odd numbers have something left over
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
it is a even number it ends in 0,2,4,6 or 8 when it is odd it ends in 1,3,5,7 or 9
It is a negative number. The answer is the same whether there is an odd or even number of addends.
