You can put this solution on YOUR website!
You'd do better with some examples but here's a couple,
\n" ); document.write( "10 more than a number, \"10%2BN\"
\n" ); document.write( "20 less than twice a number, \"2%2AN-20\"
\n" ); document.write( "is means \"=\",
\n" ); document.write( "10 more than a number is 20 less than twice the same number \"10%2Bn=2%2An-20\"
\n" ); document.write( "
\n" );
