Evaluate using BODMAS:
`18-:(7-4)-:2xx6`

Answer

To evaluate the expression `18 -: (7 - 4) -: 2 x 6` using the BODMAS rule, we will follow these steps:

### Step 1: Solve the bracket
First, we need to solve the expression inside the brackets:
\[ 7 - 4 = 3 \]

### Step 2: Rewrite the expression
Now, we can rewrite the expression with the result from the bracket:
\[ 18 -: 3 -: 2 x 6 \]

### Step 3: Perform division from left to right
Next, we will perform the division operations from left to right. The first division is:
\[ 18 -: 3 = 6 \]

Now, we rewrite the expression again:
\[ 6 -: 2 x 6 \]

### Step 4: Perform the next division
Now, we perform the next division:
\[ 6 -: 2 = 3 \]

Now, we rewrite the expression:
\[ 3 x 6 \]

### Step 5: Perform the multiplication
Finally, we perform the multiplication:
\[ 3 x 6 = 18 \]

### Final Answer
Thus, the final answer is:
\[ \text{Answer} = 18 \]
