1. 7 + ((-1) × 3) – 3 – 102. -20 + 7 + (7 + (-3 × 3 ))3. ((-20) : ( -4 )) × (-5) +3
Jawaban:
1. –9
2. –15
3. –22
Penjelasan dengan langkah-langkah:
1. 7 + ((-1)×3) – 3 – 10
= 7 + (-3) – 3 – 10
= 4 – 3 – 10
= -9
2. -20 + 7 + (7+(-3×3))
= -20 + 7 + (7+(-9))
= -13 + (-2)
= -15
3. ((-20) : (-4)) × (-5) + 3
= 5 × (-5) + 3
= -25 + 3
= -22
