Algebra.Com's Answer #199912 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! If 'a' is negative, then -a is the opposite of a negative number which means that -a is positive. Eg: if a=-2, then -a=-(-2)=2\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Remember that the absolute value of ANY number is ALWAYS positive. So |-a| is positive regardless if 'a' is positive or negative.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "On the flip side, since absolute values are always positive, the opposite of an absolute value is negative. So -|a| is negative since |a| is positive.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Likewise, since |-a| is also positive (see above), -|-a| is negative since -|-a| is the opposite of |-a|. \n" ); document.write( " |
