\n" ); document.write( "\n" ); document.write( "When you subtract a negative number it is the same as adding it, so:\r
\n" ); document.write( "\n" ); document.write( "\"18%2F24-%28-14%2F24%29=32%2F24-21%2F24=11%2F24\"\r
\n" ); document.write( "\n" ); document.write( "watch your signs, it can get tricky when you go to fast. Remember when subtacting a negative number you add it.
