   You see the correct answers below to the left of the == operator

   ( some_variable  !=  8 ) == ( ! ( some_variable  == 8 ) )
   ( some_variable  >  10 ) == ( ( some_variable - 10 )  >  0 )
   ( some_variable  <= 88 ) == ( some_variable  <  88  ||  some_variable  ==  88 )
   ( some_variable  <  other_variable ) == ( ( some_variable - other_variable )  <  0 )
   ( some_variable  <  99 ) == ( ! ( ! ( some_variable  <  99 ) )
