Dart supports different data types for different tasks. Like in life, we use words to communicate and numbers to calculate.

Dart allows us to use numbers for mathematical operations:

We can use the `bool` data type to print whether a statement is `true` or `false`:

In the future, we will learn to work with all types of data, and in the following chapters we will consider the simplest of them.

For example, we can perform mathematical operations between `int` and `double` because both are numbers.


However, we cannot add a `String` to an `int` or `double` because a `String` is simply a sequence of characters, which does not support mathematical operations.
