Question

tinh nhanh :(235-47)+(175-53)

Answer 1

( 235 - 47 ) + ( 175 - 53 )

= 235 - 47 + 175 - 53 

= [ 235 - 175 ] + [ -47 - ( -53 ) ]

= 60         +            6

= 66 

Vậy kết quả là 66

Answer 2

\(\left(235-47\right)+\left(175-53\right)\)

\(=235-47+175-53\)

\(=235+175-47-53\)

\(=410-\left(47+53\right)\)

\(=410-100\)

\(=310\)

Answer 3

(235-47)+(175-53)

=235-47+175-53

=(235+175)-(47+53)

=410-100
