Question

6-(-9+7-1)-[3-(-5+4+6)-1]=
28-[21-(12-3)-7]=
[-2+3•(2-5):3]-[(3-5+2)-2(3-4)]
8-[6-(-3+7)-6]+4​

Answer 1

Respuesta:

6-(-9+7-1)-[3-(-5+4+6)-1] = 12

28-[21-(12-3)-7] = 23

[-2+3•(2-5):3]-[(3-5+2)-2(3-4)] = -3

8-[6-(-3+7)-6]+4​ = 16  

Answer 2

Respuesta:

6-(-9+7-1)-[3-(-5+4+6)-1] = 12

28-[21-(12-3)-7] = 23
