 `COUNT` is commonly used to quickly get an overview of the volume of data in a table, such as the total number of orders placed in a `sales` dataset.
 
 ```sql
-SELECT COUNT(*) FROM sales.orders;
+SELECT COUNT(*) 
+FROM sales.orders;
 ```
 
 The result of this query is a single numeric value representing the total number of orders (or rows) present in the `sales.orders` table.
 
 ```sql
-SELECT COUNT(DISTINCT country) FROM sales.customers;
+SELECT COUNT(DISTINCT country) 
+FROM sales.customers;
 ```
 
 This SQL query uses the `COUNT` function along with the `DISTINCT` keyword to determine the number of unique countries present in the `country` column of the `sales.customers` table. Essentially, it counts each distinct `country` only once, providing a numerical result that represents the total number of different countries in the dataset.

 `SUM` is a versatile aggregate function widely used for calculating the total sum of values in a numeric column. Whether you're analyzing financial data or evaluating inventory quantities, `SUM` provides a straightforward way to aggregate numbers across multiple rows in a table.
 
 ```sql
-SELECT SUM(price) FROM sales.products;
+SELECT SUM(price)

 The `AVG` function is an essential SQL aggregate function designed to calculate the arithmetic mean of numeric values within a column. Whether you're dealing with product prices, employee salaries, or exam scores, `AVG` enables you to summarize data efficiently by returning a single value that represents the average of all rows in the specified dataset.
 
 ```sql

 This query is designed to calculate the average `price` of all products listed in the `sales.products` table. By using the `AVG` function, it computes the arithmetic mean of the values in the `price` column, effectively summarizing the dataset into a single representative value.

 The `MAX` and `MIN` functions are aggregate functions used to identify the highest and lowest numeric values within a column.
 
 ```sql

 ```
 
 This query retrieves two values: the highest `price` and the lowest `price` among all products listed in the `sales.products` table.
