Looks great! Thank you for working on this. However, I had some more suggestions if its not too much to ask

[cristian-aldea]

💡 Same for the one below

Suggested change

	Integer actual = operations.addOrSub(2, 6);
	Integer expected = 8;
	assertEquals(expected, actual);
	assertEquals(8, operations.addOrSub(2, 6));

Might as well shorten this code in the interest of quality :^)

Instead of

if (a > b) {
        return a - b;
} else {
	return a + b;
}

Do

return a > b ? a - b : a + b;

Not agree with this. The use of the ternary operation affects code readability is not a recommended practice.

Ah my bad you're right, nevermind my comment then

[bit172]

I agree. Unless you are a 10x developer, those changes would affect code readability.
