Tentukan hasil dari a. 15 + (5 × (−6)) b. 12 × (−7) + (−16) ÷ (−2) c. −15 ÷ (−3) − 7 × (−4)

a. 15 + ( 5 x ( −6 ))
= 15 + ( -30 )
= 15 - 30
= -15

b. ( 12 x ( −7 )) + (( −16 ) : ( −2 )
= -84 + 8
= -76

c. ( −15 : ( −3 )) − ( 7 x ( −4 ))
= 5 - ( -28 )
= 5 + 28
= 33

a. 15+(5x(-6))
=15-30
=-15
b. 12x(-7)+(-16):(-2)
=-84+8
=-76
c. -15:(-3)-7x(-4)
=5+28
=33
