64-6[15+2(-3+8)] ... Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "64-6[15+2(5)] ... Add -3 to 8 to get 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "64-6[15+10] ... Multiply 2 and 5 to get 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "64-6[25] ... Add 15 to 10 to get 25\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "64-150 ... Multiply -6 and 25 to get -150\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-86 ... Subtract 150 from 64 to get -86\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So 64-6[15+2(-3+8)] = -86
\n" ); document.write( "
\n" );
