Fill each cell inside a polyomino by the size of the polyomino, after applying all mathematical operations it contains (multiplication/division before addition/subtraction). For example, a 5-square polyomino containing -3 and ×2 will have the number 5×2-3 = 7 on each of its cells. Polyominoes that contain the same number may not be <a href="/puzzles/terminology#adj">orthogonally adjacent</a>.</p>

<p><b>EDIT: VERSION 5 fajshnkkbkxmidcvger</b> I hope it&#8217;s the last update. I&#8217;m pretty sure it has a unique solution, but my intended solution requires a really large-scale (as in the whole thing) deduction <i>as the first step</i>. And hence, the expert time is doubled. Whee.</p>
<p>Erm. So I lied and posted a new puzzle before April. This was made while I was doing chemistry finals (after completing it).</p>
<p>Yes, I believe that 6.5/10 is accurate for a 7&#215;7 grid, but I didn&#8217;t give this to my testsolvers so I don&#8217;t know what the others think. I&#8217;m giving this now, and I&#8217;ll edit the difficulty/time later after getting responses.</p>
<p>If you find the rules hard to understand, I suppose I should post an example&#8230;</p>
<p>Also, did you notice <a href="https://chaosatthesky.wordpress.com/2013/03/23/p028/">Puzzle 28</a> and <a href="https://chaosatthesky.wordpress.com/2013/03/23/fff-25/">FFF 25</a> are redone? (The originals were broken and I gave up finding a way to fix them.)</p>
