Jawaban:
A).17+(-5)x30=
17+(-150)=
17-150=-133
B).25-(-45):(-9)=
25-5=20
C).8+(-56):7=
8+-8=
8-8=0
D).10x(4+(-19))=
10x(4-19)=
10x-15=-150
E).85:(-17)+6x(-15)=
-5+-90=-95
Penjelasan dengan langkah-langkah:
a. 17 – (5 x 30) = 17 – 150 = – 133
b. 25 + (45 : – 9) = 25 + (- 5) = 25 -5 = 20
c. 8 – (56 : 7) = 8 – 8 = 0
d. 10 x (4 – 19) = 10 x – 15 = – 150
e. (85 x – 17) + (6 x – 15) = – 1,445 – 90 =
– 1,535
