Java Unit Testing in Java How to Test Using Before to not repeat yourself

Instantiated calculator, not recognized and is throwing compiler errors

Might be some syntax error I'm not seeing but it looks fine

com/example/CalculatorTest.java
package com.example;

import org.junit.Before;
import org.junit.Test;

import static org.junit.Assert.*;

public class CalculatorTest {

    @Before
    public void setUp() throws Exception {
        Calculator calculator = new Calculator();
    }

    @Test
    public void addingMultipleNumbersProducesResult() throws Exception {

        int answer = calculator.addNumbers(1 ,2, 3);

        assertEquals(6, answer);
    }

    @Test
    public void addingSingleNumberTotalsAppropriately() throws Exception {

        int answer = calculator.addNumbers(1);

        assertEquals(1, answer);
    }
}
com/example/Calculator.java
package com.example;

public class Calculator {

    public int addNumbers(int... numbers) {
        int total = 0;
        for (int number : numbers) {
            total += number;
        }
        return total;
    }
}
