If A stands for +, B stands for - ,C stands for `xx` , then what is the value of (10 C4) A (4 C 4 ) B 6?

Options

A. 60
B. 56
C. 50
D. 20

Explanation

To solve the expression \( (10 \, C \, 4) \, A \, (4 \, C \, 4) \, B \, 6 \), where \( A \) stands for \( + \), \( B \) stands for \( - \), and \( C \) stands for \( \times \) (multiplication), we will follow these steps:

### Step 1: Replace the symbols with their meanings
The expression can be rewritten as:
\[ (10 \times 4) + (4 \times 4) - 6 \]

### Step 2: Calculate the multiplication in the brackets
First, we calculate \( 10 \times 4 \) and \( 4 \times 4 \):
\[ 10 \times 4 = 40 \]
\[ 4 \times 4 = 16 \]

### Step 3: Substitute the results back into the expression
Now, we can substitute these values back into the expression:
\[ 40 + 16 - 6 \]

### Step 4: Perform the addition
Next, we perform the addition:
\[ 40 + 16 = 56 \]

### Step 5: Perform the subtraction
Finally, we subtract 6 from the result:
\[ 56 - 6 = 50 \]

### Final Answer
Thus, the value of the expression is:
\[ \boxed{50} \]
