Question

Soluciona cada polinomio eliminando signos de agrupación:
(150 - 20) x 40 + 30 (60 ÷ 3) - 180 ÷ (100 - 10) =
(80 - 20 + 5 + 100 - 50 ÷ 10) + 90 x 60 ÷ 20 =
[(80 – 20) ÷ 5 + (100 - 50) ÷ 10] + 90 x 60 + 20 =
1200 + 40 x (50 - 20) + 10 (10 x 20) + 60 (20 + 10)} =
{500 - [450 – (40 - 20) × 10 + 100 ÷ 5]} =

Answer 1

Explicación paso a paso:

1.

(150 - 20) x 40 + 30 (60 ÷ 3) - 180 ÷ (100 - 10)

30 x 40 + 30(20) - 180 ÷ 90

1200 + 600 - 2

1800 - 2

1798

2.

(80 - 20 + 5 + 100 - 50 ÷ 10) + 90 x 60 ÷ 20

(80 - 20 + 5 + 100 - 5) + 5400 ÷ 20

160 + 270

430

3.

[(80 – 20) ÷ 5 + (100 - 50) ÷ 10] + 90 x 60 + 20

[60 ÷ 5 + 50 ÷ 10] + 5400 + 20

12 + 5 + 5400 + 20

5437

4.

1200 + 40 x (50 - 20) + 10 (10 x 20) + 60 (20 + 10)}

1200 + 40 x 30 + 10(200) + 60(30)

1200 + 1200 + 2000 + 1800

6200

5.

{500 - [450 – (40 - 20) × 10 + 100 ÷ 5]}

{500 - [450 - 20 x 10 + 20]}

{500 - [450 - 200 + 20]}

{500 - 270]

230
