If you take a number
\n" ); document.write( "

\r\n" );
document.write( "Call this original number by a letter, say,\r\n" );
document.write( "\r\n" );
document.write( "      N\r\n" );
document.write( "

\n" ); document.write( "and add a zero to the right
\n" ); document.write( "

\r\n" );
document.write( "To annex a zero on the right is to multiply it by 10.\r\n" );
document.write( "\r\n" );
document.write( "So this is \r\n" );
document.write( "\r\n" );
document.write( "    10N\r\n" );
document.write( "

\n" ); document.write( "and subtract the result from 143,
\n" ); document.write( "

\r\n" );
document.write( "That gives \r\n" );
document.write( "\r\n" );
document.write( "   143 - 10N\r\n" );
document.write( "

\n" ); document.write( "you’ll get three times the original number.
\n" ); document.write( "

\r\n" );
document.write( "So we have the equation\r\n" );
document.write( "\r\n" );
document.write( "   143 - 10N = 3N\r\n" );
document.write( "

\n" ); document.write( "What is the number?
\n" ); document.write( "

\r\n" );
document.write( "   Add 10N to both sides:\r\n" );
document.write( "\r\n" );
document.write( "     143 = 13N\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 13\r\n" );
document.write( "\r\n" );
document.write( "     11 = N\r\n" );
document.write( "\r\n" );
document.write( "Edwin

\n" ); document.write( "

\n" );
