If the mathematical operators `-, +, xx` and `-:` are represented by G, P, U and S respectively, then find the value of
48 S 8 P 7 U 2 G 21

Options

A. 0
B. `-1`
C. 20
D. `-21`

Answer

To solve the expression \( 48 S 8 P 7 U 2 G 21 \) using the given operators, we first need to replace the operators with their corresponding mathematical symbols:

- \( S \) represents division \( (/) \)
- \( P \) represents addition \( (+) \)
- \( U \) represents multiplication \( (\times) \)
- \( G \) represents subtraction \( (-) \)

Now, we can rewrite the expression:

\[ 48 S 8 P 7 U 2 G 21 \implies 48 / 8 + 7 \times 2 - 21 \]

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

1. **Division**
2. **Multiplication**
3. **Addition**
4. **Subtraction**

### Step 1: Perform Division
Calculate \( 48 / 8 \):

\[ 48 / 8 = 6 \]

### Step 2: Perform Multiplication
Now calculate \( 7 \times 2 \):

\[ 7 \times 2 = 14 \]

### Step 3: Substitute Back into the Expression
Now substitute these results back into the expression:

\[ 6 + 14 - 21 \]

### Step 4: Perform Addition
Calculate \( 6 + 14 \):

\[ 6 + 14 = 20 \]

### Step 5: Perform Subtraction
Now subtract \( 21 \) from \( 20 \):

\[ 20 - 21 = -1 \]

Thus, the final value of the expression \( 48 S 8 P 7 U 2 G 21 \) is:

\[ \boxed{-1} \]
