Answer 1

[gấu zuka (siêu quậy)]

59*267-67*31-67*28

59*267(67*31-67*280)

59*267-67*(61+28)

59*267-67*59

59*(267-67)

59*200

=11800

Answer 2

[Nguyễn Vũ Minh Hiếu]

\(59.267-67.31-67.28\)

\(=59.267-\left(67.31+67.28\right)\)

\(=59.267-\left[67.\left(31+28\right)\right]\)

\(=59.267-\left[67.59\right]\)

\(=59.267-67.59\)

\(=59.\left(267-67\right)\)

\(=59.200\)

\(=11800\)
