Directions: Solve the question based on the redefined mathematical operators.

In a custom computational system, standard arithmetic operators are redefined as follows:
+ denotes multiplication (×)
- denotes addition (+)
× denotes division (÷)
÷ denotes subtraction (-)

Based on these rules, find the value of the following expression:
(18 + 5) × (6 - 4) ÷ 4 = ?

The correct answer is 5.

Given the rules for redefined mathematical operators:
• '+' denotes multiplication (×)
• '-' denotes addition (+)
• '×' denotes division (÷)
• '÷' denotes subtraction (-)

We are required to find the value of the expression:

$(18+5)\times (6-4)÷4$

Replacing the original operators with their redefined meanings, the expression becomes:

$(18\times 5)÷(6+4)-4$

Now, follow the standard order of operations (BODMAS/PEMDAS) to solve step-by-step:

Step 1: Evaluate the operations inside the brackets:

$18\times 5=90$

$6+4=10$

Step 2: Substitute the evaluated bracket values back into the expression:

$90÷10-4$

Step 3: Perform the division operation:

$90÷10=9$

Step 4: Perform the subtraction operation:

$9-4=5$

Therefore, the value of the given expression is 5.
