You can put this solution on YOUR website!
placement of parentheses can make a huge difference, for example you wrote this:\r
\n" ); document.write( "\n" ); document.write( "1-(4/x+2)÷1-(1/x-1)\r
\n" ); document.write( "\n" ); document.write( "which converts to\r
\n" ); document.write( "\n" ); document.write( "\"1-%284%2Fx%2B2%29%2F1-%281%2Fx-1%29\"\r
\n" ); document.write( "\n" ); document.write( "but I think you meant to write:\r
\n" ); document.write( "\n" ); document.write( "(1-4/(x+2))/(1-1/(x-1))\r
\n" ); document.write( "\n" ); document.write( "which converts to\r
\n" ); document.write( "\n" ); document.write( "\"%281-4%2F%28x%2B2%29%29%2F%281-1%2F%28x-1%29%29\"}\r
