Simplify the following (1 to 6) :
`(-3)xx(-12)div(-4)+3xx6`.

Answer

To simplify the expression \((-3) \times (-12) \div (-4) + 3 \times 6\), we will follow the order of operations, often remembered by the acronym BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Identify the operations**: The expression consists of multiplication, division, and addition.
\[ (-3) \times (-12) \div (-4) + 3 \times 6 \]

2. **Perform the division first**: According to BODMAS, we will first handle the division part of the expression.
\[ (-12) \div (-4) = 3 \]
Now, substitute this back into the expression:
\[ (-3) \times 3 + 3 \times 6 \]

3. **Perform the multiplications**: Next, we will perform the multiplications from left to right.
- First multiplication:
\[ (-3) \times 3 = -9 \]
- Second multiplication:
\[ 3 \times 6 = 18 \]
Now, substitute these results back into the expression:
\[ -9 + 18 \]

4. **Perform the addition**: Finally, we will add the results together.
\[ -9 + 18 = 9 \]

### Final Answer:
The simplified result of the expression \((-3) \times (-12) \div (-4) + 3 \times 6\) is \(9\).
