Question 1047929
<pre>
You wrote this:

M={x x is an integer and &#8722;5&#8804;x&#8722;3}

But that is incomplete.  There should be either a 
vertical line | or a colon : between the x's on the
left.

Also there should be either a < or a &#8804; between the
x and the -3 on the right. 

If you meant this:

M = {x | x is an integer and &#8722;5 &#8804; x < &#8722;3}

Then the answer is  {-5, -4}

But if you meant this:

M = {x | x is an integer and &#8722;5 &#8804; x &#8804; &#8722;3}

Then the answer is {-5, -4, -3}
