hello

should I take zero as an even integer
there are some cases in which zero is considered as an even integer and calculated to solve the question
and in other question, it doesn't
I could not find a pattern for solution( or question) that takes or doesn't take zero as an even integer

Is there any rule?

hi soodia

0 is always an even integer, 3 is odd but 30 is even because unit's digit is 0
Can you provide some example where 0 is not considered as even?

Dear soodia,

I'm happy to respond. :-)

My friend, it's very important to distinguish when the question is talking about an "integer" and when it is talk about a "positive integer." The number zero is always an integer, but it is also the only number on the number line that is neither positive nor negative, so it would be excluded if "positive" were stipulated.

The even integers are { . . . -8, -6, -4, -2, 0, 2, 4, 6, 8, . . .}

The even positive integers are {2, 4, 6, 8, 10, 12, 14, . . . }

I don't know whether this answers your question. If it doesn't, I am going to ask you to post the exact text of different questions, some where you feel zero is included and some where you feel zero is excluded. In math, precision is everything, and every word of the prompt of a question needs to be regarded with the same precision.

Does all this make sense?
Mike :-)
