tjnrrrrrrr
Procedimiento:
a)
35 + [ 74 – 5 x (54 ÷ 6 +18) x 5 – 20] =
35 + [ 74 – 5 x (9 +18) x 5 – 20] =
35 + [ 74 – 5 x (27) x 5 – 20] =
35 + [ 74 – 135 x 5 – 20] =
35 + [ 74 – 675 – 20] =
35 + [ 74 – 675 – 20] =
35 + [– 601 – 20] =
35 + [– 621] =
35 – 601 =
- 586
b)
{19 + 20 x [81 – 44 + (59 – 60 ÷ 20) + 8] x 5} =
{19 + 20 x [81 – 44 + (59 – 3) + 8] x 5} =
{19 + 20 x [81 – 44 + (56) + 8] x 5} =
[19 + 20 x (81 – 44 + 56 + 8) x 5] =
[19 + 20 x (37 + 56 + 8) x 5] =
[19 + 20 x (93 + 8) x 5] =
[19 + 20 x (101) x 5] =
(19 + 20 x 101 x 5) =
(19 + 2020 x 5) =
(19 + 10,100) =
10,119 =
c)
45 + [10 – 15 + (20 x 40) + 34] + 6 x 8 – (9 x 15) – 12 =
45 + [10 – 15 + (800) + 34] + 6 x 8 – (135) – 12 =
45 + (10 – 15 + 800 + 34) + 6 x 8 – 135 – 12 =
45 + (– 5 + 800 + 34) + 6 x 8 – 135 – 12 =

{25 + [30 x (35 + 40) – 45] + 50 x 55} – 60 =
[25 + (30 x 75 – 45) + 50 x 55] – 60 =
[25 + (2250 – 45) + 50 x 55] – 60 =
(25 + 2205 + 50 x 55) – 60 =
(25 + 2205 + 2750) – 60 =
(2230 + 2750) – 60 =
(2230 + 2750) – 60 =
