Question

Tính

(35 - 17) - (-17 + 20 + 35)

Answer 1

(35 - 17) - (-17 + 20 + 35)

=35-17+17-20-35

=35-35-17+17-20

=-20

Answer 2

\(\left(35-17\right)-\left(-17+20+35\right)\\ =18-\left(3+35\right)\\ =18-38\\ =-20\)

Answer 3

(35-17)-(-17+20+35)

=35-17+17-20-35

=(35-35)+[(-17)+17] -20

=-20

Answer 4

\((35 - 17) - (-17 + 20 + 35)\)

\(=(35 - 17) +(17 + 20 + 35)\)

\(=(35-36)+(17-17)-20\)

\(=0+0-20\)

\(=-20\)

Answer 5

( 35  -  17 )  - ( - 17 + 20 + 35 )

= 35 - 17 + 17 - 20 - 35

= 35 - 35 - 17 + 17 - 20

= - 20
