Answer 1

Răspuns:

b) 3−2(5−3(4−( −2 ): (- 1)) )

=3 −2* (5 −3*(4−2))  = 3  −2* (5−(3)* (2))   = 3−2*(5−6)   =  3−(2*(−1))   = 3−(−2)  = 5

d) −52+ 3 :  (7 - (4 : -1) = -52 + 3 : ( 7- ( -4)) = -52 + 3 : 11 = - 569 / 11

D) 5−(23 +(−7)−2−(1−6)) = 5−(16−2−(1−6))  =5−(14−(1−6))  =5−(14−(−5))  =5−19  = - 14

h) (−2)*(−4)−32*(2−3*(−4+6)) = 8−32*(2−3*(−4+6))  =8−32*(2−(3)*(2))  =8−32(2−6)

=8−(32)*(−4)  =8−(−128)  = 136

j) −(+4)−(12 − 81 : ( 1 - 2 + 51 -1 -11) = - 4 - ( 12 - 81 : ( -1 + 51 - 1 -11) = - 4 - ( 12 - 81 : ( 50 - 1 -11)  = - 4 - ( 12 - 81 / 38) = - 4 - 375 / 38 = - 527 / 38
