$\"+%28-7%29+%2B+6+%2B+%28-%282-3%29%29+\"$
\n" ); document.write( "The rule to follow when you have parentheses within
\n" ); document.write( "parentheses is -start with the innermost parenthesis
\n" ); document.write( "In your problem, the innermost is $\"+%282-3%29+\"$
\n" ); document.write( "which equals $\"+-1+\"$ . Now you have
\n" ); document.write( " $\"+%28-7%29+%2B+6+%2B+%28-%28-1%29%29+\"$
\n" ); document.write( "A minus in front of a parenthesis changes the sign
\n" ); document.write( "of everything inside, like this:
\n" ); document.write( " $\"+-%28+a+-+b+%2B+c+-+d%29+=+-a+%2B+b+-+c+%2B+d+\"$
\n" ); document.write( "So, now you have
\n" ); document.write( " $\"+%28-7%29+%2B+6+%2B+%28+1+%29+\"$
\n" ); document.write( "Note also that if no sign appears in front of a number
\n" ); document.write( "then a + is implied
\n" ); document.write( "Also, you don't need the ( ) around the 1 or the 7
\n" ); document.write( " $\"+-7+%2B+6+%2B+1+=+-7+%2B+7+\"$
\n" ); document.write( " $\"+-7+%2B+7+=+0+\"$ answer \n" ); document.write( "

\n" );
