Is 2468101213 odd or even?
If the last number is odd or even then the whole number is odd or even, in this case the last number is 3 which is an odd number, therefore the whole number is odd.
Is 3 even or odd?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 3 is an odd number.
If you add 3 to an even number the sum would be odd or even?
Odd. Even + Even = Even Odd + Odd = Even Odd + Even = Even + Odd = Odd
Can 3 odd numbers ever add up to an even number?
No, because two odd numbers always add together to be an even number, and a even plus an odd number is an odd number, example: 3+1+11=An even number? 3+1=4 4+11=15 Is 15 even? No. 3+1+11= An odd number (15)
What 7 odd numbers that will total 30?
You cannot do this, because you're taking odd numbers: if you add two odd numbers together, you will get an even number. Take the odd numbers in pairs, so you'll have 3 pairs plus an extra odd number. The 3 pairs make 3 even numbers. You can add up any number of even numbers and get an even number, so you will have an even + odd, which is odd. 30 is an even number, but your result will be odd, no matter what 7 odd numbers you choose.
