Answer 1

Respuesta:

A) (20 – 4 X 2 ) ( 8 – 3 X 5)=

(20 – 4 X 2 ) ( 8 – 3 X 5)=

(16 x 2 ) (5 x 5)=

(16 x 2 ) (5 x 5)=

32 x 25=

800

B) 2.5 ( 4 + 6 X 6 )=

2.5 (10 X 6 )=

2.5 x 60=

150

C) 2 { ( 18 – 6 X 4 ) + [ 3 – ( 6 ÷ 2 – 2 ) ] }=

2 { ( 12 X 4 ) + [ 3 – ( 3 – 2 ) ] }=

2 { ( 12 X 4 ) + [ 3 – (-1) ] }=

2 { ( 12 X 4 ) + [ 3 + 1 ] }=

2 { ( 48 ) + [ 4 ] }=

2 { 56 }=

112

D) 4 { 2[ 3 – ( 2 X 1 )]}=

4 { 2[ 3 – ( 2 )]}=

4 { 2[ 3 – 2]}=

4 { 2[ 1]}=

4 { 2 x 1}=

4 { 2}=

8

E) 5 ( 3 ( 5 – 2 X 1 ) )=

5 ( 3 ( 3 X 1 ) )=

5 ( 3 ( 3 ) )=

5 ( 3 x 3 )=

5 ( 9 )=
