Understanding the order of operations is crucial when simplifying mathematical expressions. It serves as a rule book for which steps to tackle first to avoid any confusion and to get the correct answer. In mathematics, we follow the PEMDAS/BODMAS rule, which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

For example, looking at the given expression, we first address the exponentiation before dealing with multiplication or division. Only after these steps do we manage the addition or subtraction, ensuring we have the right answer at the end. Keeping the order of operations in mind is like following a map; if you go in the right direction, you'll reach your destination without any mishaps.

Exponentiation is a form of arithmetic operation that involves raising a number, known as the base, to a power, which is the exponent. It simplifies repeated multiplication, as the exponent tells us how many times to multiply the base by itself. For instance, in the expression \(6^2\), 6 is the base, and 2 is the exponent, which translates to multiplying 6 by itself once, since \(6^2 = 6 \times 6 = 36\).

It's important to perform exponentiation before multiplication, division, addition, or subtraction when it appears in an expression. This aligns with our order of operations rule, ensuring each step in simplifying an expression builds off the previous step correctly.

The bedrock of simplifying expressions involves arithmetic operations such as addition, subtraction, multiplication, and division. They are the tools we use to break down complex expressions into simpler ones or to evaluate equations. When we look at the steps to simplify an expression, like \(3 \times 36 - 5\), we are left with multiplication and subtraction. These operations are straightforward: multiplying 3 by 36 gives us 108, and subtracting 5 from 108 gives us 103.

It is essential to execute these arithmetic operations with care, respecting the hierarchy established by the order of operations. By approaching these operations step by step, and with a clear understanding, simplifying complex mathematical expressions can be turned into a manageable and mistake-free task.
