The values are scalar values. Array of Hashes. Array of hashes is the data structure where the array has a list of hashes. Hash references are the objects of an array. In order to access the key and values, we need to de-reference them. Array of hashes is a great data structure if we want to loop through hashes numerically.

The next line: $grades{"Foo Bar"}{Mathematics} = 97; This creates a key-value pair in the %grades hash where the key isFoo Bar and the value is a reference to another, internal hash.A hash that does not have a name.
