You can put this solution on YOUR website!
Let's re-write it like this,
\n" ); document.write( "\"10%2B50=80-A\"
\n" ); document.write( "\"60=80-A\"
\n" ); document.write( "What number subtracted from 80 gives you 60?
\n" ); document.write( "\"A=20\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"90-30=20%2BB\"
\n" ); document.write( "\"60=20%2BB\"
\n" ); document.write( "What number added to 20 gives you 60?
\n" ); document.write( "\"B=40\"
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" );
