`16 div 8 xx 6 -2+12=?`

Options

A. 22
B. 24
C. 23
D. 120

Answer

To solve the expression \( 16 \div 8 \, xx \, 6 \, - \, 2 \, + \, 12 \) with the given meanings of the operations, we will first replace the operations according to the provided definitions:

1. **Replace the operations:**
- \( + \) means \( \div \)
- \( xx \) means \( - \)
- \( \div \) means \( + \)
- \( - \) means \( xx \)

Therefore, the expression \( 16 \div 8 \, xx \, 6 \, - \, 2 \, + \, 12 \) becomes:
\[ 16 + 8 - 6 \, xx \, 2 \, \div \, 12 \]

2. **Rewrite the expression:**
Now, substituting the operations, we get:
\[ 16 + 8 - 6 \, xx \, 2 \, \div \, 12 \]

3. **Evaluate the expression step by step:**
- First, we will perform the addition:
\[ 16 + 8 = 24 \]
- Now, the expression becomes:
\[ 24 - 6 \, xx \, 2 \, \div \, 12 \]
- Next, we perform the subtraction:
\[ 24 - 6 = 18 \]
- Now, the expression becomes:
\[ 18 \, xx \, 2 \, \div \, 12 \]
- Now, we will perform the multiplication (which is represented by \( xx \)):
\[ 18 \, xx \, 2 = 36 \]
- Now, the expression becomes:
\[ 36 \div 12 \]
- Finally, we perform the division:
\[ 36 \div 12 = 3 \]

4. **Final Result:**
Therefore, the final answer is:
\[ \text{The value is } 3. \]
