Bài 1: phá ngặc (ko tính nhé)
a) -[16-(73+24)+(-37)]-(-14)
b) +[-(-7-17+32)+(-34+11)]+14
c) -[-17-(14+17-6)-)75-1)
d) (-16-17) – [(68+63)+(75-1)]

a) -[16-(73+24)+(-37)]-(-14)
b) +[-(-7-17+32)+(-34+11)]+14
c) -[-17-(14+17-6)-)75-1)
d) (-16-17) – [(68+63)+(75-1)]
a,
$-[16-(73+24)+(-37)]-(-14)$
$=-(16-73-24-37)+14$
$=-16+73+24+37+14$
b,
$+[-(-7-17+32)+(-34+11)]+14$
$=(7+17-32-34+11)+14$
$=7+17-32-34+11+14$
c,
$-[-17-(14+17-6)-(75-1)$
$=-(-17-14-17+6)-75+1$
$=17+14+17-6-75+1$
d,
$(-16-17)-[(68+63)+(75-1)]$
$=-16-17-(68+63+75-1)$
$=-16-17-68-63-75+1$
`a) -[16-(73+24)+(-37)]-(-14)`
`= -16+(73+24)-(-37)+14`
`= -16+73+24+37+14`
`b) +[-(-7-17+32)+(-34+11)]+14`
`= +7+17-32-34+11+14`
`c) -[-17-(14+17-6)-)75-1)`
`= +17+(14+17-6)+(75-1)`
`= +17+14+17-6+75-1`
`d) (-16-17) – [(68+63)+(75-1)]`
`= -16-17 – (68+63)-(75-1)`
`= -16-17 – 68-63-75+1`
(Chúc bạn học tốt nha)
