\(\left(-51+\left|13\right|\right)-\left(13-\left|-51\right|-2018\right)\)
\(=\left(-51+13\right)-\left(13-51-2018\right)\)
\(=-38-\left(-2056\right)\)
\(=2018\)
=_51+13_13+51+2018
=(_51+51)+(13_13)+2018
=0+0+2018
2018
(_ la dau tru)
(-51+|13|)-(13-|-51|-2018)
=(-51+13)-(13-51-2018)
=[(-51+13)-(13-51)]-2018
=0-2018
=-2018
Vậy mình sai rồi. Sáng nay trượt vỏ chuối huhu thi ơi là thiiiii.
Trả lời..............
=2018
.............học tốt..................
(-51 + |13|)-(13-|-51|-2018)
=(-51+13)-(13-51-2018)
=-51+13-13+51+2018
=.(51-51)+(13-13)+2018
=0+0+2018
=2018
