Temos que seguir um procedimento matemático, onde as adições e subtrações são resolvidas primeiro e depois a multiplicação dos fatores e por último as divisões, portanto:
{ [ ( 40 + 35 ) ( 10 ) : 4 ] : [ ( 14 ) ( 31-133) ] } =
{ [ ( 75) (10) : 4 ] : [ (14) (-102) ] } =
{ [ 750 : 4 ] : [ -1428]} =
{ 187,5 : -1428 } =
-0,1
Lembrando que se resolve de dentro pra fora, parênteses, colchetes e chaves.

40 + 35.(10/4/14).31 - 133
40 - 133 + 35.(10/4/14).31
- 93 +35.(10/4/14).31
- 93 + 35.31.(10/4/14)
- 93 + 1085.(10/4/14)
- 93 + 1085.(10/4).(1/14)
- 93 + 1085.(10/56)
- 93 + 1085.(5/28)
- 93 + (5425/28)
- 93 + (775/4)
[4.( - 93) + 775]/4
(- 372 + 775)/4
403/4 = 100,75

40+(((35x10)/4)/(14x31))-133=40+((350/4)/128)-133=40+(350/(4x128))-133=40+(350/512)-133=40+(0,683)-133=-92,31

40 + ((((35 * 10) / 4) / 14) * 31) - 133
40+(((350/4)/14)*31)-133
40+((87,5/14)*31)-133
40+(6,25*31)-133
(40+193,75)-133
233,75-133=100,75
