In a certain symbolic code, if the symbol ‘@’ stands for multiplication (×) and the symbol ‘$’ stands for addition (+), then evaluate the expression: 8 @ 3 $ 4 = ?

The correct answer is 28.

To evaluate the given symbolic expression, let us substitute the symbols with their corresponding mathematical operators as defined in the question:

1. The symbol ‘@’ represents multiplication ($\times$).
2. The symbol ‘$’ represents addition ($+$).

Now, let us rewrite the given expression by replacing the symbols with their respective mathematical operations:

$8@3\$4$

Replacing ‘@’ with $\times$ and ‘$’ with $+$ gives:

$8\times 3+4$

According to the standard order of operations (BODMAS / PEMDAS), multiplication takes precedence over addition. Therefore, we evaluate the multiplication step first:

$8\times 3=24$

Next, perform the addition step by adding 4 to the result:

$24+4=28$

Thus, the final value of the expression is 28.
