9 x 9 + 9 : 9
= 81 + 9 : 9
= 81 + 1
= 82

14 + 14 – 14 x 2
= 14 + 14 – 28
= 28 – 28
= 0

Jawaban:

9 × 9 + 9 ÷ 9 = 82

14 + 14 – 14 × 2 = 0

Penjelasan dengan langkah-langkah:

9 × 9 + 9 ÷ 9

• = (9 × 9) + (9 ÷ 9)
• = 81 + 1
• = 82

___________________

14 + 14 – 14 × 2

• = 14 + 14 – (14 × 2)
• = 14 + 14 – 28
• = (14 + 14) – 28
• = 28 – 28
• = 0
