When we talk about the distance between 2 numbers, we usually just subtract those numbers to find the distance between them, so:
\r
\n" ); document.write( "\n" ); document.write( "|x-7|<=4
\r
\n" ); document.write( "\n" ); document.write( "In words, the absolute value of x minus 7 is less than or equal to 4 (it can be 4, but it can't larger than 4, that is why we use less than or equal to).
\r
\n" ); document.write( "\n" ); document.write( "We don't know if x or 7 is the bigger number, and when talking about distances, they can most often never be negative, that is where the absolute value comes in to play.
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps! :) \n" ); document.write( "

\n" );
