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

Sure, let's solve the problem step by step.

1. First, we need to decode the symbols:

   • A stands for +
   • B stands for -
   • C stands for *

2. Replace the symbols in the expression with their corresponding operations:

   • (10C4) becomes (10 * 4)
   • (A) becomes +
   • (4C4) becomes (4 * 4)
   • (B) becomes -

3. Substitute these into the expression:

   • (10 * 4) + (4 * 4) - 6

4. Now, perform the operations inside the parentheses:

   • 10 * 4 = 40
   • 4 * 4 = 16

5. Substitute these results back into the expression:

   • 40 + 16 - 6

6. Finally, perform the addition and subtraction:

   • 40 + 16 = 56
   • 56 - 6 = 50

So, the value of the expression is 50.
