<p>Mathleague.com says it is not..."Positive integers are all the whole numbers greater than zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of these whole numbers: -1, -2, -3, -4, -5,"</p>
<p>Many CCers say that it is.</p>
<p>This is for the question that had to do with how many integers solve this equation: It was either 3 or 4 depending on if 0 is an integer.</p>
<p>0 is an integer.</p>
<p>Integer - A member of the set of positive whole numbers 1, 2, 3,... , negative whole numbers -1, -2, -3,... , and zero {0}.</p>

<p>0 is an integer...just not positive. Of course, that doesn't mean 0 is disqualified from being a possible value. It was...</p>
<p>grammatix says 0 is an integer</p>
<p>I thought it was any whole number.</p>
<p>Zero is DEFINITELY an integer.</p>
<p>Zero is.....
-An integer
-Even
-Not prime
-Not positive or negative
-A whole number</p>
<p>how is it not prime? I have no clue, that's why I 'm asking</p>
<p>0 and 1 are not considered prime.</p>
<p>2 is the first prime, and the only even prime.</p>
<p>That's just the rule - I guess its because with 0 and 1 - there are no other numbers that could possibly be factors. With 2 - it probably just fits that formula they use for finding the next primes and stuff.</p>
<p>The question also asked for any real numbers, not integers. Either way, it was 4. =</p>
<p>I agree - it was definitely 4.</p>
<p>@rcman13: you're description for zero is fine except for it being an even number, zerio is neither even nor odd...</p>
<p>In fact, zero is considered even if you are considering the set of integers or natural numbers. Not if you are considering the set of whole numbers. Sort of weird stuff - google it and see what you find - interesting.</p>
<p>
a prime is defined to a number with two and only two distinct factors.</p>
<p>1 is not prime, because its only factor is 1.
0 is not prime, because it has an infinite number of factors (0<em>1, 0</em>2, ...)</p>
<p>aaahhh..even I thought 0 was not an integer. Here we go another mistake again!</p>
<p>0 by definition is an integer. But is not an opposite integer. 0, -0 = 0
whereas 10, -10 are opposites.</p>
<p>According to the College Board's Official SAT Study Guide, p. 228, zero is an even integer.</p>
<p>Zero is not considered positive - to whoever stated it before. It is neither positive nor negative.</p>
<p>Zero is an integer.</p>
<p>What is the point of reviving a year old thread that is this stupid?</p>
