In a certain mathematical coding language, if '+' denotes multiplication, '×' denotes subtraction, '-' denotes division, and '÷' denotes addition, then determine the value of the expression:
Correct Answer :
57
Solution :
The correct answer is Option 3: 57.
To solve this mathematical coding problem, we need to decode the given operators according to the rules specified in the question and then evaluate the resulting expression using the BODMAS/PEMDAS rule (Order of Operations).
Step 1: Understand the Symbol Replacements
From the given information, we have:
• '+' denotes multiplication (×)
• '×' denotes subtraction (-)
• '-' denotes division (÷)
• '÷' denotes addition (+)
Step 2: Rewrite the Expression
The original expression is:
Replacing the symbols with their actual mathematical operations gives:
Step 3: Evaluate the Decoded Expression using Order of Operations
First, perform the division operation ():
Now the expression becomes:
Next, perform the multiplication operation ():
Now the expression becomes:
Finally, perform the addition and subtraction from left to right:
Thus, the final value of the given expression is 57.
