Explicación paso a paso:

a) –6 x (–12+(–5)) = -6*(-12-5) = -6*-17 = -102

b) –27 – (–8) x (–6) x (–38) = -27+8*(-6)*(-38) = -19*-6*(-38) = -114*-38 = -4332

c) 2850 ÷ (((-27) + 9) – (4 x (58–72))) =

= 2850 ÷ (((-27+ 9) – (4 x (-14))) = 2850 ÷ (((-18) – (4 x -14))) =

2850 ÷ ((-18) – (-56))= 2850 ÷ (-18+56) = 2850 ÷ 38 = 75

d) - 4823 ÷ ((93 – 168) – 16) x (626 - 1010) =

-4823 ÷ ((-75) – 16) x -384) = -4823 ÷ ((-75– 16) x -384) =

-4823 ÷ (-91 x -384) = -4823 ÷ -34944 = $-\frac{53}{384}$

e) 56 x ((– 9 + 8) + (4 – 1)) ÷ 7 = 56 x ((-1) + (3)) ÷ 7 = 56 x (-1+3) ÷ 7

56 x (2) ÷ 7 = 56 x (2) ÷ 7 = 112÷ 7 = 16

f) –10 x ((– 1– 5) – (8x (–5 – 3))) ÷ (–2) = –10 x ((-6) – (8x (-8))) ÷ (–2) =

–10 x ((-6) – (8x-8))) ÷ (–2) = –10 x ((-6) – (-64))) ÷ (–2) =

–10 x ((-6+64))) ÷ (–2) = –10 x (56) ÷ (–2) = -560÷ (–2) = -280

g) 7 x (16–(–5)) – 94 ÷ (5 – 3) = 7 x (16+5)) – 94 ÷ (2) =

7 x (21) – 94 ÷ (2) = 147-47 = 100

h) 68 x ((3–2) x (15–46)) –60858 ÷ (543–(-2103)) =

68 x ((1) x (-31)) –60858 ÷ (543+2103)) =

68 x (1x-31) –60858 ÷ 2646 = 68 x (-31) –60858 ÷ 2646

-2108–23 = -2131
