Answer

To solve the expression \(1^{(@)} + 2^{(@)} + 3^{(@)}\), we need to determine the value of the expression when \( @ = 0 \).

### Step-by-Step Solution:

1. **Identify the Expression**: We have \(1^{(0)} + 2^{(0)} + 3^{(0)}\).

2. **Apply the Exponent Rule**: According to the property of exponents, any non-zero number raised to the power of 0 is equal to 1. This means:
- \(1^{(0)} = 1\)
- \(2^{(0)} = 1\)
- \(3^{(0)} = 1\)

3. **Calculate Each Term**:
- For \(1^{(0)}\):
\[ 1^{(0)} = 1 \]
- For \(2^{(0)}\):
\[ 2^{(0)} = 1 \]
- For \(3^{(0)}\):
\[ 3^{(0)} = 1 \]

4. **Sum the Results**: Now, we add the results of each term together:
\[ 1 + 1 + 1 = 3 \]

5. **Final Result**: Therefore, the value of the expression \(1^{(0)} + 2^{(0)} + 3^{(0)}\) is:
\[ 3 \]
