You can put this solution on YOUR website!
$\"abs%28t-230%29%3C=10\"$ where $\"t\"$ = temperature of the engine in degrees Fahrenheit says that the difference between the temperature of the engine and 230 should be no more than 10 degrees Fahrenheit.

\n" ); document.write( " $\"abs%28t-230%29%3C=10\"$ means that
\n" ); document.write( "either $\"0%3C=t-230%3C=10\"$ ,
\n" ); document.write( "or
\n" ); document.write( " $\"0%3C-%28t-230%29%3C=10\"$ , which is equivalent to
\n" ); document.write( " $\"0%3Et-230%3E=-10\"$ and to $\"-10%3C=t-230%3C0\"$ .
\n" ); document.write( "The two inequalities can be written together as
\n" ); document.write( " $\"-10%3C=t-230%3C=10\"$ .
\n" ); document.write( "Adding 230 to all 3 sides, you get
