Bài 6.Tính:

a) 12 – (10 -19) ; b) (-27) – (13 -19).

c) 14 – (-15) – 21 ; d) (- 27) + 16 -1

ai giải hộ mình với 

 

Answer 1

a) 12-(10-19)

= 12 - -9

= 21

b (-27) - ( 13 -19 )

= -27--6

= -21

c) 14-(-15)-21

=29 -21

=8

d)(-27) +16-1

= -11-1

=-12

Answer 2

a) 12 - (10 - 19) = 12 - (-9) = 12 + 9 = 21

b) (-27) - (13 - 19) = (-27) - (-6) = (-27) + 6 = -21

c) 14 - (-15) - 21 = 14 + 15 - 21 = 29 - 21 = 8

d) (-27) + 16 - 1 = (-11) - 1 = -12

Answer 3

-37+54+(-70)+(-163)+246

Answer 4

\(\text{a)12-(10-19)}\)

\(=12-\left(-9\right)\)

\(=21\)

\(\text{b)(-27)-(13-19)}\)

\(=\left(-27\right)-\left(-6\right)\)

\(=-21\)

\(\text{c)14-(-15)-21}\)

\(=29-21\)

\(=8\)

\(\text{d)(-27)-(13-19)}\)

\(=\left(-27\right)-\left(-6\right)\)

\(=-21\)
