Respuesta :
Dominique:
-3-14
=-3+14 ( this step is incorrect as we cannot write a-b = a+b )
=11 ( incorrect answer)
Juan:
-3-14
=-3+(-14) ( this step follows the rule a-b =a+(-b) )
=-17 (correct)
dominiques has found that
-3-14=-3+14 where he has made a mistake of writing =14 instead of -14
juan has written that -3-14=-3+(-14)=-17 where he has written that answer correctly.
where the product of (-) *(+)=-
juan is right.
