Question

Tính nhanh: 179 - (46 + 179) + [(187 - 27) - 187 - (-46 + 73)]

Answer 1

\(179-\left(46+179\right)+\left[\left(187-27\right)-187-\left(-46+73\right)\right]\)

\(=179-46-179+\left[187-27-187+46-73\right]\)

\(=-46+\left[-27+46-73\right]\)
\(=-46-27+46-73\)

\(=-100\)

Answer 2

`179-(46+179)+[(187-27)-187-(-46+73)]`

`=179-46-179+(187-27-187+46-73)`

`=179-46-179+187-27-187+46-73`

`=-27-73=-100`
