Follow the BODMAS rule to solve this question, as per the order given below:

Step-1: Parts of an equation enclosed in 'Brackets' must be solved first and in the bracket,

Step-2: Any mathematical 'OF' or 'Exponent' must be solved next,

Step-3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated,

Step-4: Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

**Calculation: **

⇒ 18[11 ÷ {24 ÷ 4 - 5 ÷ (3 - 1/3)}]

⇒ 18[ 11 ÷ {6 - 5 ÷ 8/3}]

⇒ 18[11 ÷ {6 - 15/8}]

⇒ 18[11 ÷ 33/8]

⇒ 18[11 × 8/33]

⇒ 18 × 8/3

⇒ 48

So, Product of digit

⇒ 4 × 8 = 32
