tjnrrrrrrr

Answer 2

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 =

45 + (795 + 34) + 6 x 8 – 135 – 12 =

45 + 829 + 6 x 8 – 135 – 12 =

45 + 829 + 48 – 135 – 12 =

874 + 48 – 135 – 12 =

922 – 135 – 12 =

787 - 12 =

775 =

d)

{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 =

4980 - 60 =

4920 =
