 $i$ 行目を考える時、$a_i$ を入れるか入れないかの二択になります。
 
 - $a_i$ を入れないときは、何も変わらないので一個上のセルの値の真偽値そのままです。つまり、$i$ 行 $j$ 列の真偽値は、$i-1$ 行 $j$ 列の真偽値となります。
-- $a_i$ を入れるときは、$a_k(1\leq k\leq i-1)$ を使って、**$j-a_i$** を作ることができていれば、それに $a_i$ を加えることで $j$ を作れそうです。
+- $a_i$ を入れるときは、$\{a_k\}(1\leq k\leq i-1)$ を使って、**$j-a_i$** を作ることができていれば、それに $a_i$ を加えることで $j$ を作れそうです。
   例えば、$3$ と $4$ を使って、$10-6=4$ が作れていれば、それに $6$ を加えることで $10$ を作ることができます。
   そうすると、$i$ 行 $j$ 列の真偽値は、$i-1$ 行 $j-a_i$ 列の真偽値となります。
