<p>The answer to this problem doesn't make sense, especially after reading Amu's explanation.</p>
<p>Amu says 0 is not a positive integer, which I agree.</p>
<p>but he says the two correct points are (2,0) and (1,1).</p>
<p>i know 1,1 is correct because both numbers are positive, but how is (2,0) correct?</p>
<p>the problem is</p>
<p>For how many ordered pairs of positive integers (x,y) is 2x+3y<6</p>
