Answer (170)
d=13-[12-4x(-1)-7]x(5-7,5)
d = 13 -(12 +1-7) x(-2.5)
d = 13 -(6) x -2.5
d = 13 +15
d = 28
e=4+2x[-3x(5x7)-9
e = 4 +2 x(-3x25-9)
e = 4 +2x(-75-9)
e = 4 +2x(-84)
e = 4 -168
e = -164
c=3,4-(17-19)x(-1,7-5,1)
c = 3.4 -(-2) x(-6.8)
c = 3.4 -(+13.6)
c = 3.4-13.6
c = -10.2
d = 13 -(12 +1-7) x(-2.5)
d = 13 -(6) x -2.5
d = 13 +15
d = 28
e=4+2x[-3x(5x7)-9
e = 4 +2 x(-3x25-9)
e = 4 +2x(-75-9)
e = 4 +2x(-84)
e = 4 -168
e = -164
c=3,4-(17-19)x(-1,7-5,1)
c = 3.4 -(-2) x(-6.8)
c = 3.4 -(+13.6)
c = 3.4-13.6
c = -10.2
d = 13 - [12 - 4 x (-1) - 7] x (5 - 7,5)
d= 13 - [12 + 4 - 7] x -2,5
d= 13 - 9 x -2,5
d = 13 + 22,5
d = 35,5
e = 4 + 2 x [-3 x (5 x 7)] - 9
e= 4 + 2 x [-3 x 35] - 9
e = 4 + 2 x -105 - 9
e = 4 + 210 - 9
e = 205
c = 3,4 - (17 - 19) x (-1,7 - 5,1)
c = 3,4 + 2 x -6,8
c = 3,4 + 13,6
c = 17
d= 13 - [12 + 4 - 7] x -2,5
d= 13 - 9 x -2,5
d = 13 + 22,5
d = 35,5
e = 4 + 2 x [-3 x (5 x 7)] - 9
e= 4 + 2 x [-3 x 35] - 9

e = 205
c = 3,4 - (17 - 19) x (-1,7 - 5,1)
c = 3,4 + 2 x -6,8
c = 3,4 + 13,6
c = 17
