If A means ‘+’, B means ‘×’, C means ‘−' and D means ‘÷’, then what will be the value of the following expression? 16 D 4 A 4 B 2 C 2
Let's break down the expression step by step, replacing the letters with their corresponding arithmetic operations:
The expression is: 16 D 4 A 4 B 2 C 2
Substituting the symbols with operations, we get:
16 ÷ 4 + 4 × 2 − 2
Following the order of operations (division, multiplication, addition, subtraction), we calculate:
- Division: 16 ÷ 4 = 4
- Multiplication: 4 × 2 = 8
- Addition: 4 + 8 = 12
- Subtraction: 12 − 2 = 10
Therefore, the value of the expression is 10.
The correct answer is 10. This problem tests your understanding of basic arithmetic operations and the order of operations (PEMDAS/BODMAS). It is crucial to follow the correct order to arrive at the accurate solution. Remember that division and multiplication are performed before addition and subtraction. Incorrectly applying the order of operations will lead to an incorrect answer. This question emphasizes the importance of precise calculation and logical sequencing in solving mathematical problems. Careful substitution and sequential calculation is key to success. The problem highlights the need for careful reading and accurate interpretation of symbolic representations. Misinterpreting the symbols would lead to the wrong answer.
