Tentukan hasil operasi hitung campuran dengan penjelasannya A. 7 x ( -15+5) = B. 12 + ( -15) x (-4) = C. -24 – 14 x ( -10 ) = D. 26- ( -40) : ( -5) =
a.) 7 x (-15 + 5)
→ 7 x (-15 + 5)
→ 7 x (-10)
→ -70
b.) 12 + ( -15) x (-4)
→ 12 + ( -15) x (-4)
→ 12 + 60
→ 72
c.) -24 – 14 x ( -10)
→ -24 – 14 x ( -10)
→ -24 – (-140) = -24 + 140
→ -24 + 140 = 140 – 24
→ 116
d.) 26 – (-40) : (-5)
→ 26 – (-40) : (-5)
→ 26 – 8
→ 18
mohon maaf apabila terdapat kesalahan
semoga membantu ^ ^
PENYELESAIAN SOAL !
A. 7 x ( -15+5)
= 7 x (-10)
= -70
B. 12 + ( -15) x (-4)
= 12 + 60
= 72
C. -24 – 14 x ( -10 )
= -24 – (-140)
= -24 + 140
= 116
D. 26- ( -40) : ( -5)
= 26 – 8
= 18
