Expanding Expressions

So far we have seen expressions using the Int type. We will need quite a few more types, and a lot more expressions, to create the kind of expressive programs we're aiming for.

In this chapter we will:

• learn about literal expressions and use them to create more of Scala's basic types;
• learn about objects and methods which we'll use to create compound expressions;
• see the operator style of method calls; and
• learn more about how types relate to compound expressions.

For this chapter you can continue to use the worksheet we've already created.
