Let \"+n+\" = number of rows
\n" ); document.write( "\"+n+-+10+\" = seats in each row
\n" ); document.write( "——————-
\n" ); document.write( "I can say:
\n" ); document.write( "\"+n%2A%28+n+-+10+%29+=+1200+\"
\n" ); document.write( "\"+n%5E2+-+10n+-+1200+=+0+\"
\n" ); document.write( "\"+%28+n+-+40+%29%2A%28+n+%2B+30+%29+=+0+\" ( by inspection )
\n" ); document.write( "\"+n+=+40+\"
\n" ); document.write( "And
\n" ); document.write( "\"+n+-+10+=+30+\"
\n" ); document.write( "There are 30 seats in each row
\n" ); document.write( " \n" ); document.write( "
\n" );
