2. [ ( 9 – 4 ) ÷ 5 + (10 – 2) ÷ 4 ] + (12 x 6 ÷ 18) + 2
3. (9 + 3 ])x 5 – 2 ÷ (3 – 2 ) – (8 x 6 ÷( 4 ÷ 2) + 5)
4. [ 15 + (8 – 3 )x 5] ÷ [(8 – 2) ÷ 2 + 7 ]
5. ( 5 x 4 x 3 ) ÷(15 - 3 ) + 18 ÷ (11 – 5 )x 3

Answer 1

Respuesta:

1. -12

2. 14

3. 29

4. 4

5. 14

Explicación paso a paso:

1. ( (-15÷3) x( 6-2) x 3) ÷ (15÷(-3))

( (-5) × (4) × 3) ÷ ( - 5)

( 60 ÷ (- 5))

- 12

2. [ ( 9 – 4 ) ÷ 5 + (10 – 2) ÷ 4 ] + (12 x 6 ÷ 18) + 2

[ ( 5 ) ÷ 5 + ( 8 ) ÷ 4 ] + (72 ÷ 8) + 2

[ 1 + 2 ] + 9 + 2

[ 3] + 9 + 2

14

3. (9 + 3 ) x 5 – 2 ÷ (3 – 2 ) – (8 x 6 ÷( 4 ÷ 2) + 5)

( 12 ) × 5 - 2 ÷ ( 1 ) - (8 × 6 ÷ ( 2 ) + 5)

60 - 2 - (48 ÷ 2 + 5)

60 - 2 - ( 24 + 5)

60 - 2 - 29

29

4. [ 15 + (8 – 3 )x 5] ÷ [(8 – 2) ÷ 2 + 7 ]

[ 15 + 5 × 5 ] ÷ [ 6 ÷ 2 + 7 ]

[ 15 + 25 ] ÷ [ 3 + 7]

40 ÷ 10

4

5. ( 5 x 4 x 3 ) ÷(15 - 3 ) + 18 ÷ (11 – 5 )x 3

60 ÷ 12 + 18 ÷ 6 x 3

5 + 3 × 3

5 + 9

14
