How to test multiple return values, using Jest

I'm looking manipulate values from a byte stream. I will receive values in an array, that I'm looking to parse. I'm looking to return a dictionary with the new formatted results. My formatting code is called index.js

//index.js
function calculateNumbers(numbers)
{   
  results={};
  
  //Summing two values
  sumOfTwo = numbers[0] + numbers[1];  //should be 6
  results.valTwo = sumOfTwo;

  //Summing three values
  sumOfThree = numbers[0] + numbers[1] + numbers[3]; //should be 9
  results.valThree = sumOfThree;

  return{
    total:results
  };
}

module.exports = calculateNumbers;

For testing I want create a test script to validate my responses (Shown in index.test.js.)

In my function I'm returning {value:total}; When returning my values in this format my test code returns saying:

 Expected: 3
    Received: {"value": {"valThree": NaN, "valTwo": 3}}

//index.test.js
const calculateNumbers= require("./index");
test("Returns calculations",()=> {
    //expect(0.2 + 0.1).toBeCloseTo(0.3, 5);
    expect(calculateNumbers([1,2,6])).toBe(3,9);

});

How can I modify my unit test to parse the new returned value ?

Result of your function is object. You need to assert all object:

expect(calculateNumbers([1,2,6])).toStrictEqual({
  total: {
    valTwo: 3,
    valThree: 9,
  },
});
