Answer 1

It gives correct answer.
It is just that the input is taken as a string so 'z' is added as a string to the result. If I give 'z' as 3 then according to your code, it will return 213 since 6+15=21 and 3 is concatenated to it.
Instead of passing just 'z', do parseInt(z).

Answer 2

document.write(plus(6, 15, parseInt(z)));

Answer 5

You could also do something like: var z = Number(prompt("Enter the last number:")); it'll take the user input and convert it from a string to int and store it as an int to the variable z.
