<p>Is 0 a multiple of all numbers?</p>

<p>i don’t think so…these stupid properties of number terror me</p>

<p>Yea, it is, but that might not be the answer to your problem. Was this created in response to a question from the blue book? If so, you should post it.</p>

<p>Reasoning is rather simple:</p>

<p>Let x, y, and z be any integer such that x = y * z. If x = 0 and y is assigned any real number such that 0 = y * z, you will find that if z = 0 the answer is always correct. Therefore, 0 is a multiple of every number.</p>

<p>No, it’s from Princeton Review</p>

<p>Which of the following must be true?
I. The sum of two consecutive integers is odd.
II. The sum of three consecutive integers is even.
III. The sum of three consecutive integers is a multiple of 3.</p>

<p>So for III, I was thinking about -1, 0, and 1. The sum of the three is 0 and I thought it wasn’t a multiple of three, but the answer says it’s I and III.</p>

<p>hey liebenasuka, are u doing the 11 PR practice tests?</p>

6

<p>not yet. It’s from the princeton book with 3 tests</p>

7

<p>the PR practice tests are incredibly hard!. much harder than the 10 REAL SAT’s</p>

8

<p>Yea lieben, I and III are both correct. 0 * 3 = 0, therefore 0 is a multiple of three.</p>

<p>^ thank you</p>

<p>lol,i am going to take the PR test from tomorrow</p>
