1. a) Ta có:  −19−|+13|+|−10|−(−5)−11

   = −19−13+10+5−11

   = −28

   b) Ta có: (−10)−(11)+|−5|−|−7|−8

   = −10−11+5−7−8

   = −31

   c) Ta có:  −(−8)−(+7)−|−11|+|+12|

   = 8−7−11+12

   = 2

   d) −14−|−18|−(−20)−|−25|

   = −14−18+20−25

   = −37

   đ) 23−|−15|−(−17)+|−13|

   = 23−15+17+13

   = 38

   Xin ctlhn về cho nhóm ạ !

2. `-19 – |+13| + |-10| – (-5) – 11`

   `= -19 – 13 + 10 +5 – 11`

   `= -28`

   `( -10) – (11) + |-5| – |-7| – 8`

   `= -10 – 11 + 5 – 7 – 8`

   `= -31`

   `- (-8) – (+7) – |-11| + |+12|`

   `= 8 – 7 – 11+ 12`

   `= 2`

   `-14 – |-18| – (-20) – |-25|`

   `= -14 – 18 +20 – 25`

   `= -37`

   `23 – |-15| – (-17) + |-13|`

   `= 23 – 15 + 17 + 13`

   `= 38`
