If + means `xx,xx` means `-,div` means + and - means `div`, then what is the value of `62-2div8+15xx4+6` ?

Options

A. 130
B. 127
C. 120
D. 128

Answer

To solve the expression \(62 - 2 \div 8 + 15 \times 4 + 6\) with the given operations switched, we first need to replace the operations according to the rules provided:

1. \(+\) means multiplication (\(\times\))
2. \(\times\) means subtraction (\(-\))
3. \(\div\) means addition (\(+\))
4. \(-\) means division (\(\div\))

Now, let's rewrite the expression with the new operations:

- The original expression is \(62 - 2 \div 8 + 15 \times 4 + 6\).
- Replacing the operations:
- \(62 - 2\) becomes \(62 \div 2\)
- \(2 \div 8\) becomes \(2 + 8\)
- \(15 \times 4\) becomes \(15 - 4\)
- \(+ 6\) becomes \(\times 6\)

So, the expression now reads:

\[62 \div 2 + 8 + 15 - 4 \times 6\]

Next, we will follow the order of operations (BODMAS/BIDMAS):

1. **Division**: Calculate \(62 \div 2\):
\[ 62 \div 2 = 31 \]

2. **Addition**: Now add \(31 + 8\):
\[ 31 + 8 = 39 \]

3. **Subtraction**: Next, calculate \(15 - 4\):
\[ 15 - 4 = 11 \]

4. **Multiplication**: Now multiply \(11 \times 6\):
\[ 11 \times 6 = 66 \]

5. **Final Calculation**: Now, we have \(39 - 66\):
\[ 39 - 66 = -27 \]

Thus, the final value of the expression \(62 - 2 \div 8 + 15 \times 4 + 6\) is \(-27\).
