🔹 Set A :

1️⃣ 6 ÷ 3 + 4 × 2

• 6 ÷ 3 = 2 → 4 × 2 = 8 → 2 + 8 = 10

2️⃣ 6 × 4 − 12 ÷ 3 − 8

• 6 × 4 = 24 → 12 ÷ 3 = 4 → 24 − 4 − 8 = 12

3️⃣ 4 × 4 − 3 × 3 − 16 ÷ 4

• 4 × 4 = 16 → 3 × 3 = 9 → 16 − 9 = 7 → 16 ÷ 4 = 4 → 7 − 4 = 3

4️⃣ 20 − (3 × 23 − 5)

• 3 × 23 = 69 → (69 − 5) = 64 → 20 − 64 = −44

5️⃣ (5 + 2)² − 9 × 3 + 2³

• (5 + 2)² = 7² = 49 → 9 × 3 = 27 → 2³ = 8 → 49 − 27 + 8 = 30

6️⃣ (7 − √9) × (42 − 3 + 1)

• √9 = 3 → (7 − 3) = 4 → (42 − 3 + 1) = 40 → 4 × 40 = 160

🔹 Set B :

1️⃣ 5 × (2² + 3) + (2³)²

• 2² = 4 → (4 + 3) = 7 → 5 × 7 = 35 → 2³ = 8 → 8² = 64 → 35 + 64 = 99

2️⃣ 6 × 2 + 5 × 1 + 4 ÷ 2 − 1

• 6 × 2 = 12 → 5 × 1 = 5 → 4 ÷ 2 = 2 → 12 + 5 + 2 − 1 = 18

3️⃣ 1 + (2 × (4 − 3 + 1) + 7) − 2

• (4 − 3 + 1) = 2 → 2 × 2 = 4 → 4 + 7 = 11 → 1 + 11 − 2 = 10

4️⃣ 10 + 6 × (3 − 2) × 8 ÷ 24 − 1

• (3 − 2) = 1 → 6 × 1 × 8 ÷ 24 = 48 ÷ 24 = 2 → 10 + 2 − 1 = 11

5️⃣ (20 − 18)³ ÷ 8 × 3 − 1

• (20 − 18) = 2 → 2³ = 8 → 8 ÷ 8 = 1 → 1 × 3 = 3 → 3 − 1 = 2

6️⃣ (2 + 1 − 3 + 1 + 4)² − 2 × 4

• (2 + 1 − 3 + 1 + 4) = 5 → 5² = 25 → 2 × 4 = 8 → 25 − 8 = 17
