1. -12 : 2 + -12 x 2

Jawaban:

1. -12 : 2 + -12 x 2 = 6+-24=-30

2. -12 : (8-12) x 2= -12:-4×2=3×2=6

3. (-12 – (-6)) : (8+ (-10)) = -6:-2=3

4. (20-(5)) x (-14 – (-10)) = 15×4=60

maaf kalau slh

Penjelasan dengan langkah-langkah:

Nomer 1

-12 : 2 + (-12) × 2

= -6 + (-24)

= – 30

Nomer 2

-12 : (8 – 12) × 2

= -12 : (-4) × 2

= 3 × 2

= 6

Nomer 3

(-12 – (-6)) : (8 + (-10))

= -6 : (-2)

= 3

Nomer 4

(20 – (5)) × (-14 – (-10))

= 15 × -4

= -60

Nomer 4 benar (20 – (5)) atau (20 – (–5)) ??

Kalo (20 – (–5)) seperti ini =

(20 – (-5)) × (-14 – (-10))

= 25 × -4

= -100
