When I do a sum of numbers, it returns them together, as if they were text strings, does anyone know what I'm doing wrong?

Question

//Creating the class
class Persons {
constructor(name, age, email, city, working){
this.name = name;
this.age = age;
this.email = email;
this.city = city;
this.working = working;
}
//Method to see the characteristics of the user
show() {
console.log("Name: " + this.name);
console.log("Age: " + this.age);
console.log("Email: " + this.email);
console.log("City: " + this.city);
console.log("Working: " + this.working);
}
}
//Saving objects in variables
const person1 = new Persons("Max", 24, "[e-mail]", "Washington", true);
const person2 = new Persons("Matt", 21, "[e-mail]", "Portland", true);
console.log(person1.show());
console.log(" ");
console.log(person2.show());

//To see the sum of ages
function sumAge(age) {
let agePeople = {
age1: person1.age,
age2: person2.age
};
console.log("The sum of ages is: " + agePeople.age1 + agePeople.age2);
}
sumAge();

Answer 1

Yes, just like in my example. Put the numeric calculation in parentheses.
console.log("The sum of ages is: " + (agePeople.age1 + agePeople.age2));

Answer 2

When you concatenate a string to a number the number is implicitly converted to a string.
"Nums: " + 4 + 2
This concatenates from left to right, so that 4 is first converted to a string effectively changing it to;
"Nums: 4" + 2
Then it is repeated for the next number so the result is;
"Nums: 42"
In or to give the calculation higher precedence you can put it in parentheses like;
"Nums: " + (4 + 2)
Now the calculation will occur then the concatenation.
"Nums: " + 6
Then to;
"Nums: 6"

Answer 3

Thanks friend, it served me just as you said, you clarified this part for me that I had no idea how to fix.

Answer 4

Thanks Chaotic Dawg, would you know how to implement this solution in the code?, If you can.

Answer 5

You could also use a comma to separate them for the console.log output like;

conaole.log("The sum of ages is:", agePeople.age1 + agePeople.age2);

Note: a space will be inserted between each argument when output.
