$\"-4%2A%28-5%29%2A%28-4%29%2A%28-7%29\"$
\n" ); document.write( "to make this easy count how many negative\"-\" signs you have in the multiplication problem. Odd amount(1,3,5,7,9...) will always give u a negative number and and even amount (2,4,6,8...)will always give u a possitive number.
\n" ); document.write( "so from the problem there are 4 negative signs so you know the answer will be possitive.
\n" ); document.write( "so then u can rewrite the problem as $\"4%2A5%2A4%2A7\"$
\n" ); document.write( "now simply multiply in order
\n" ); document.write( " $\"4%2A5=20\"$
\n" ); document.write( " $\"20%2A4=80\"$
\n" ); document.write( " $\"80%2A7=560\"$
\n" ); document.write( "so 560 is the answer \n" ); document.write( "

\n" );
