whats 6.022x^23 - 2.3567x10^-35 / 6.022x10^23

If by   -2.3567 x 10^-35 / 6.022 x 10^ 23    you mean    ( -2.3567 x 10^-35 ) / ( 6.022 x 10^ 23 ),

this part of the problem becomes ( -2.3567 ) / (  10^35 x 6.022 x 10^ 23 ),

which becomes  ( -2.3567 ) / (  6.022 x 10^ 57 ),

which is so small that it does not affect  6.022 X 10^23,     (if that is what you meant to type)

so that is the answer.
