dominique and Juan are finding 314 whos correct explain reasoning whats the answerto this Im so confused please someone clarify class=

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.
