Looking at the ones digits:
\n" ); document.write( " $\"0%3C=B%3C=9\"$
\n" ); document.write( " $\"9%2B3%2B0%3C=9%2B3%2BB%3C=9%2B3%2B9\"$
\n" ); document.write( " $\"12%3C=9%2B3%2BB%3C=21\"$
\n" ); document.write( "Since the ones digit of $\"9%2B3%2BB\"$ is $\"3\"$ ,
\n" ); document.write( " $\"9%2B3%2BB=13\"$ --> $\"12%2BB=13\"$ --> $\"B=13-12\"$ --> $\"highlight%28B=1%29\"$
\n" ); document.write( "When adding the tens digits, we have the $\"1\"$ ten from $\"9%2B3%2BB=13\"$ carried over.
\n" ); document.write( " $\"1%2BC%2B7%2B6=10A%2BA\"$
\n" ); document.write( " $\"C%2B14=%2810%2B1%29A\"$
\n" ); document.write( " $\"C%2B14=11A\"$
\n" ); document.write( "So $\"C%2B14\"$ is the multiple of $\"11\"$ $\"11A\"$ .
\n" ); document.write( "Since $\"0%3C=C%3C=9\"$ ,
\n" ); document.write( " $\"0%2B14%3C=C%2B14%3C=9%2B14\"$
\n" ); document.write( " $\"14%3C=C%2B14%3C=23\"$
\n" ); document.write( "The only $\"C%2B14=11A\"$ multiple of $\"11\"$ between $\"14\"$ and $\"23\"$ is
\n" ); document.write( " $\"11%2A2=22\"$ .
\n" ); document.write( "So $\"11A=11%2A2\"$ ---> $\"highlight%28A=2%29\"$ and
\n" ); document.write( " $\"C%2B14=22\"$ ---> $\"C=22-14\"$ ---> $\"highlight%28C=8%29\"$ .
\n" ); document.write( "Then, $\"A-B%2BC=2-1%2B8\"$ ---> $\"highlight%28A-B%2BC=9%29\"$ . \n" ); document.write( "

\n" );
