Is 0 an even interger

Test Preparation

<p>Is 0 an even integer ?
There is an SAT test question
If is an odd integer, which of the following is an even integer?
A. p-2<br>
B. p<em>P
C. p</em>p -2<br>
D. (p-2)(P-2)<br>
E. p<em>p -p
The answer is e but if p=1 then p</em>p =1 and 1*1-1 = 0 and I thought that 0 was neither even or odd and thought that 0 was not an integer</p>

<p>instead of putting zero
(leave that case)
try putting 3 leaves answer 6 which is an even integer
try putting 5 which leaves answer 20 which is an even integer</p>

<p>0 is considered an even integer. It meets all the qualities of an even integer. It is evenly multiplied or divided by 2 and if squared and you subtract 1 you get an odd number.</p>

4

<p>I don’[t understand your #2’s point. An answer has to be true for all possibilities and if 0 is not even integer it is not. The fact that there are numbers it works for does not make it correct</p>

<h1>3 thank you and the fact that this is an SAT test question makes it moot the fact is that SATs consider 0 an even integer. I have seen Math sites that disagree but that doesn’[t matter on the test.</h1>

<p>OF COURSE 0 is an even integer. (I’m a math teacher by current occupation, and as drusba correctly points out, zero meets all the usual definitional requirements for an even number.) </p>

<p>To the point of the SAT question, none of the other answer choices would be BETTER, regardless of what you think about zero, but anyway zero IS an even integer, so there is no doubt about the correct answer to the question. To exclude answer choice (e) because of forgetting about the parity of zero is a serious example of overthinking a question.</p>
