`(7 xx 6 + 5 - 15) :- 4 + 6 :- 3 - 4 + 18 :- 3`

Options

A. 12
B. 14
C. 16
D. 18

Answer

To solve the expression `(7 x 6 + 5 - 15) ÷ 4 + 6 ÷ 3 - 4 + 18 ÷ 3`, we will follow the order of operations, often remembered by the acronym BODMAS/BIDMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Evaluate the expression inside the brackets:**
- Calculate \(7 x 6\):
\[ 7 x 6 = 42 \]
- Now substitute back into the expression:
\[ (42 + 5 - 15) ÷ 4 + 6 ÷ 3 - 4 + 18 ÷ 3 \]

2. **Continue simplifying inside the brackets:**
- Calculate \(42 + 5\):
\[ 42 + 5 = 47 \]
- Now, subtract \(15\):
\[ 47 - 15 = 32 \]
- Substitute back:
\[ (32) ÷ 4 + 6 ÷ 3 - 4 + 18 ÷ 3 \]

3. **Perform the divisions:**
- Calculate \(32 ÷ 4\):
\[ 32 ÷ 4 = 8 \]
- Calculate \(6 ÷ 3\):
\[ 6 ÷ 3 = 2 \]
- Calculate \(18 ÷ 3\):
\[ 18 ÷ 3 = 6 \]
- Substitute back into the expression:
\[ 8 + 2 - 4 + 6 \]

4. **Perform the additions and subtractions from left to right:**
- Calculate \(8 + 2\):
\[ 8 + 2 = 10 \]
- Next, subtract \(4\):
\[ 10 - 4 = 6 \]
- Finally, add \(6\):
\[ 6 + 6 = 12 \]

Thus, the final value of the expression is:
\[ \boxed{12} \]
