``````function trickyReturns(input)
print("a")
if input then
print("b")
return "foo!"
end
print("c")
-- Below
if 2+2 == 4 then
print("d")
return "boo!"
end
print("e")
end

trickyReturns(false)
``````

Why is the output in this case “a c d”, when the expression “2+2 == 4” is true, and the condition only works with true?

If the condition of an if statement evaluates to `true`, then the statements of the if block are executed. If the condition evaluates to `false`, the statements of the if block are skipped.

Since `2 + 2 == 4` evaluates to `true`, so so the statements in the block are executed.
If the condition was `2 + 2 == 5`, the statements in the if block would be skipped.

If the function call was amended to:

``````print(trickyReturns(false))
``````

then the output would be:

``````"acdboo!"
``````

(the strings `"a"`, `"c"` and `"d"` being printed by the `trickyReturns` method. The print statement outside the method prints the string `"boo!"` because that is the value returned by the `trickyReturns` method)

If the method call was:

``````print(trickyReturns(true))
``````

then the output would be:

``````"abfoo!"
``````
