Any even number can be divided by two leaving no remainder. It is, therefore, of the form 2*n.
Let 2*m and 2*n be any two even numbers.
Then, 2*m + 2*n = 2*(m + n) because multiplication is distributive over addition
that is the answer is a multiple of 2 and so is even.
To add to 13 with 2 even and 1 odd number, can do 1+4+8=13
If you add an even number to an even number, you will have an even number as a result.
All multiples of even numbers will equal an even number.
There are no two even integers that equal 217, as the sum of two even integers is always even, and 217 is an odd number. Therefore, it is impossible for two even integers to add up to 217.
Any odd number can be written as an even number plus one. Any even number plus any other even number makes an even number. Add one makes an odd number. So an odd number plus an even number is always an odd number. Algebraically, any odd number can be written as 2a+ 1 where a is a whole number. Any even number can be written as 2b, where b is a whole number. Add them together, the sum is 2(a + b) + 1, which is odd.
yes
To add to 13 with 2 even and 1 odd number, can do 1+4+8=13
yes. examples: 2+2 4 6+6 12 8+8 16 542+756 1298
the answer would be equal. For example 3+5=8 which is even.
If you add an even number to an even number, you will have an even number as a result.
Any 2 consecutive will always add up to an odd number and the number given is an even number

11 is an odd number because nothing can equal to it see for example 10 is an even number because you can add 5 + 5 and that equals 10 but nothing can equal to 11
Unless this is a trick question, none of them do. Zero is an even number, so therefore no positive odd number and negative equivalent will add to form an odd number. Similarly, negative odd numbers will add to form negative even numbers, and positive odd numbers will add to equal positive even numbers. Somebody please inform me if I'm missing something simple here.
no, b/c you can think of an odd number as an even number plus one. So if you add two odd numbers, you would be adding 2 even numbers plus 2... Let # be even... (#+1) + (#+1) = (#+#) + 2 two even numbers added together are always even
