-----------------------------------------------------------
{{{-3^3-(-3/2)^3-(1/3)^2}}}=

The -3/2 is written as -1 and a 1/2 in the problem. 
The answer is -23 and 53/72 but I get -24 and 19/72.

What?  


Starting with the expression shown, {{{-3^3-(-3/2)^3-(1/3)^2}}}


{{{cross(-27-(-1)(3/2)^2-(1/3)^2)}}}, mistake in exponent

-

{{{-27-(-1)27/8-1/9}}}


{{{-27+27/8-1/9}}}
