What do the lines outside of the equation mean? Ex: |7-4|=3 or something like that.
\n" ); document.write( "---
\n" ); document.write( "That's \"absolute value of 7-3\".
\n" ); document.write( "Evaluate the numbers inside the lines.
\n" ); document.write( "Then ignore the sign.
\n" ); document.write( "---
\n" ); document.write( "Ex: |-3-7| = |-10| = 10
\n" ); document.write( "|7-2| = |5| = 5
\n" ); document.write( "=========================\r

\n" ); document.write( "Also, when I see this question \"2+2 or -2+2\"? these are just examples.
\n" ); document.write( "2+2 will always be 4
\n" ); document.write( "-2+2 will always be 0
