Newbie programming question?

[Armynavy123]

I am doing coding bat program practice and I have a question that I don't get why I am wrong. The question is...

Given two int values, return their sum. Unless the two values are the same, then return double their sum.

My code is

public int sumDouble(int a, int b) {
if (a == b) {
return(a + b * 2);
}
return(a+b);
}

Every two numbers worked except for when (2, 2) was passed in. My program returned 6 when it was supposed to return 8. What the heck happpened?!
Aghhh good call guys, thank you all for the math lesson on order of operations.

(a+b) *2. Order of operations is wrong.

The problem is worded incorrectly: "Given two int values, return their sum. Unless the two values are the same, then return double their sum. "

It should be: "Given two int values, return their sum. If the two values are the same, then return double their sum. "

The correct solution is:

public int sumDouble(int a, int b) {
return (a == b) ? (a+b)*2 : a+b;
}

The program evaluates
(a + b * 2)
as
a + (b*2)

For your program to evaluate your equation properly, it should be
((a+b)*2)
