If the mathematical operators '+' and `'xx'` are interchanged what will be the value of the equation `9div5+10-23xx2`
A. 3
B. 2
C. `-3`
D `-5`

Options

A. B
B. C
C. A
D. D

Answer

To solve the equation `9 div 5 + 10 - 23 xx 2` with the operators '+' and 'xx' interchanged, we first need to understand what the new operators will represent:

- The '+' operator will become 'xx' (multiplication).
- The 'xx' operator will become '+' (addition).

Thus, the equation `9 div 5 + 10 - 23 xx 2` will be transformed into:

`9 div 5 xx 10 - 23 + 2`

Now, let's solve this step by step:

### Step 1: Rewrite the equation
The equation becomes:
\[ 9 \div 5 \times 10 - 23 + 2 \]

### Step 2: Apply the BODMAS/BIDMAS rule
According to the BODMAS/BIDMAS rule, we perform operations in the following order: Brackets, Orders (i.e., powers and roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).

### Step 3: Perform the division
First, we perform the division:
\[ 9 \div 5 = \frac{9}{5} \]

So the equation now looks like:
\[ \frac{9}{5} \times 10 - 23 + 2 \]

### Step 4: Perform the multiplication
Next, we perform the multiplication:
\[ \frac{9}{5} \times 10 = \frac{90}{5} = 18 \]

Now the equation is:
\[ 18 - 23 + 2 \]

### Step 5: Perform the subtraction and addition
Now we perform the subtraction and addition from left to right:
1. First, subtract:
\[ 18 - 23 = -5 \]
2. Then, add:
\[ -5 + 2 = -3 \]

### Final Result
Thus, the value of the expression is:
\[ -3 \]

### Conclusion
The correct answer is C. `-3`.
