# Understanding the Order of Basic Mathematical Operations

In the realm of mathematics, grasping the fundamental sequence of operations—addition, subtraction, multiplication, and division—is pivotal. This knowledge forms the bedrock for solving complex mathematical expressions with precision and accuracy.

## Unraveling the Hierarchy: Parentheses, Powers, Multiplication, and Division

**1. Parentheses and Powers**

The essence lies in following a structured approach, initiating with parentheses and powers. These elements dictate the primary sequence of calculations within an expression.

**2. Multiplication and Division**

Upon resolving parentheses and powers, the focus shifts to multiplication and division. It's imperative to execute these operations from left to right, adhering strictly to this chronological order.

**3. Addition and Subtraction**

Finally, the sequence culminates with addition and subtraction. Similar to multiplication and division, these operations are performed from left to right, further cementing the overarching methodology of solving mathematical expressions.

## Applying the Principles: Practice Exercises

**Exercise 1: Practicing Order of Operations**

Let's delve into a few practice exercises to fortify our understanding:

- ( 25 - 6 - 9 + 7 - 3 )
- ( 14 - 5 - 9 + 7 + 2 )
- ( 26 - 6 + 9 + 7 - 12 )

## Navigating Complex Scenarios: Examples and Solutions

**Example 1: Complex Expression Evaluation**

Consider the expression ( 300:3 - 20:2 + 3 \times 4 - 2 - 7 \times 3 ). Executing the operations methodically results in a conclusive answer of 79.

**Example 2: Advanced Mathematical Calculations**

Another intricate expression, ( 90 - 2 + 9 - 8 ), when diligently solved adhering to the order of operations, yields a value of 89.
