The question is: Determine those real numbers a for which the opposite of a is the same as the reciprocal of a. I understand the difference between opposite and reciprocal, but I still don't understand what the answer would be. Any help would be greatly appreciated!!! \n" ); document.write( "

The opposite of a is -a.
\n" ); document.write( "The reciprocal of a is 1/a.
\n" ); document.write( "Set the two equal to each other and solve for a.
\n" ); document.write( " $\"-a=1%2Fa\"$
\n" ); document.write( " $\"-a%5E2=1\"$
\n" ); document.write( " $\"a%5E2=-1\"$
\n" ); document.write( "There is no real number that once you square it gives -1.
\n" ); document.write( "There is no solution. \n" ); document.write( "
