  1. r) (-6)+ (-8)
    = -(6+8)
    = -14
    u) (-115)- (-17)
    = -115+ 17
    = -98
    p) ( 13-5. $3^{3}$ + $7^{2}$ )- (13-49)
    = ( 13- 5. 27+ 49)- ( -36)
    = ( 13- 135+ 49)+ 36
    =( -122+49)+36
    = -73+36
    = -37
    s) 29. 12- 60. 2+ 31. 12
    = 348- 120+ 372
    =228+ 372
    =600
    t) 5.$5^{2}$ – 24: $2^{3}$ 
    = 5. 4- 24: 8
    = 20- 3
    $\text{=17}$

  2. $\text{Giải đáp + Lời giải và giải thích chi tiết}$
    $r)$ $(-6)+(-8) = -(6+8)=-14$
    $u)$ $(-115)-(-17)$
    $=(-115)+17$
    $=-98$
    $p)$ $(13-5.3^3+7^2)-(13-49)$
    $=(13-5.27+49)-(-36)$
    $=(13-135+49) + 36$
    $=-73+36$
    $=-37$
    $s)$ $29.12-60.2+31.12$
    $=348-120+372$
    $=228+372$
    $=600$
    $t)$ $5.2^2-24:2^3$
    $=5.4-24:8$
    $=20-3$
    $=17$
