Let's do it longhand to make certain:
\n" ); document.write( "-24 * .5 = -12
\n" ); document.write( "-12 * .5 = -6
\n" ); document.write( "-6 * .5 = -3
\n" ); document.write( "-3 * .5 = -1.5
\n" ); document.write( "-1.5 * .5 = -.075
\n" ); document.write( "-.075 * .5 = -.0375
\n" ); document.write( "-.0375 *.5 = -.01875
\n" ); document.write( "-.01875 * .5 = -.009375
\n" ); document.write( "-.009375 * .5 = -.0046875
\n" ); document.write( "-.0046875 * 5 = -.00234375
\n" ); document.write( "Adding the -24 through the -.0046875 equals 46.8853125
\n" ); document.write( ".
\n" ); document.write( "Your answer is \"-14181%2F128\" which reduces to -110.789025
\n" ); document.write( "Not sure how you got that, but you can see that when your first number is 24, it would be difficult to end up with 110.
\n" ); document.write( "(check my math) \n" ); document.write( "
\n" );
