Question

386 - (287 + 386) - (13 + 0)
Tính hợp lí

Answer 1

386 – ( 287 + 386 ) – ( 13 + 0 ) 

= 386 – 287 – 386 – 13

= ( 386 – 386 ) – ( 287 + 13 )

= 0 – 300

= -300

Answer 2

\(386-\left(287+386\right)-\left(13+0\right)=386-287-386-13=-287-13=-300\)

Answer 3

386 – (287 + 386) – (13 + 0) 

= 386 – 287 – 386 – 13

= (386 – 386) – (287 + 13)

= 0 – 300

= - 300

Answer 4

a) 386 – (287 + 386) – (13 + 0) 

= 386 – 287 – 386 – 13

= (386 – 386) – (287 + 13)

= 0 – 300

= - 300
