If L stands for +, M stands for -, N stands for x, P stands for ÷, then: 14 N 10 L 42 P 2 M 8 =

Question

Accepted Answer

To solve the expression given in the question, we need to substitute the symbols with their corresponding mathematical operations:

- L stands for + (addition)
- M stands for - (subtraction)
- N stands for x (multiplication)
- P stands for ÷ (division)

The expression given is: 14 N 10 L 42 P 2 M 8

Substituting the symbols with the operations, the expression becomes: 14 x 10 + 42 ÷ 2 - 8

Now, we follow the order of operations, which is commonly known as BODMAS/BIDMAS (Brackets, Orders (i.e., powers and roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right)).

1. **Multiplication and Division first:**
   - 14 x 10 = 140
   - 42 ÷ 2 = 21

So, the expression now is: 140 + 21 - 8

2. **Addition and Subtraction next:**
   - 140 + 21 = 161
   - 161 - 8 = 153

Therefore, the final result of the expression is 153.

**Explanation for why Option 4 is correct:**

- The calculated result of the expression is 153, which matches Option 4. This confirms that Option 4 is the correct answer.

**Explanation for why the other options are incorrect:**

1. **Option 1 (315):** This result does not match the calculated result of 153. It is incorrect because it does not follow the correct order of operations or the correct substitution of symbols.

2. **Option 2 (531):** This result is a rearrangement of digits and does not match the calculated result of 153. It is incorrect for the same reasons as Option 1.

3. **Option 3 (351):** This result is also a rearrangement of digits and does not match the calculated result of 153. It is incorrect because it does not reflect the correct calculation of the expression.

In conclusion, Option 4 is the only option that correctly represents the result of the expression when the operations are performed in the correct order.
