Using the BODMAS rule,

B – Bracket in order (), {}, []

O – of

D – Division

M – Multiplication

A – Addition

S - Subtraction

(4 × 6 – 18 ÷ 3) × [192 ÷ {(5 + 3) × 4} – 2]

(24 – 6) × [192 ÷ {8 × 4} – 2]

⇒ 18 × [192 ÷ 32 – 2]

⇒ 18 × [6 – 2]

⇒ 18 × 4

∴ (4 × 6 – 18 ÷ 3) × [192 ÷ {(5 + 3) × 4} – 2] = 72
