Should b not be let?

Variable b should be made a constant since it never changes Hence let b = value Alternatively the answer should accept both let and var in the declaration of b.

If that was your only code, your version would work since 30 is the only number b is. However, this code is meant to be reusable as you will see if you continue in Swift. Other parts of the program would be able to change "b" and return a different sum (the whole point in using variables). B should be a var. Otherwise you may as well just type: print(10 + 30) or even just print(40)
