  1. Giải đáp:
     $\text{a) -29-11-82-6}$
    $\text{=-(29+11)-(82+6)}$
    $\text{=(-40)-88}$
    $\text{= -(40+88)}$
    $\text{= -128}$
     $\text{ b) 48-23-(-20)-11}$
    $\text{= 48-23+20-11}$
    $\text{= 25+9}$
    $\text{= 34}$
    $\text{ c) 102-(-33)-(-7)-4}$
    $\text{ = 102+33+7-4}$
    $\text{ = (102-4)+(33+7)}$
    $\text{ = 98+40}$
    $\text{ = 138}$
    $\text{d) -71-(-4)-22-10}$
    $\text{= (-71)+4-22-10}$
    $\text{= (-67)-32}$
    $\text{= -99}$
    $\text{#BEST}$
