Jawaban:
15 + 25 × 6
= 15 + 150
= 165
2³ + 10² - 50
= (2×2×2) + (10×10) - 50
= (4×2) + 100 - 50
= 8 + 100 - 50
= 108 - 50
= 58
1. perkalian didahulukan terlebih dahulu lalu pertambahan.
2. Bilangan berpangkat dikerjakan terlebih dahulu lalu ditambah dan dikurang
= (2 × 2 × 2) + (10 × 10) - 50
= (4 × 2) + 100 - 50
