Berapakah hasil dari -6 + (6:2) - ((-3) x 3)?

6.Hitunglah hasil operasi berikut.
a.(-12 + 17) x 8 + 12
b.24 x (-12) :4 - (-10)
c.120:(-10) x 8 + (-20)​

Penjelasan dengan langkah-langkah:

5. -6 + (6:2) - ((-3) x 3)

= -6 + 3 - (-9)

= -3 + 9

= 6

6a. (-12 + 17) x 8 + 12

= (-204) x 8 + 12

= -1.632 + 12

= -1.620

b. 24 x (-12) :4 - (-10)

= (-288) : 4 + 10

= -72 + 10

= -62

c. 120 : (-10) x 8 + (-20)

= (-12) x 8 - 20

= -96 - 20

= -116
