Question 12
Use the order of operations to simplify this expression

First, let’s tackle that expression step by step! Start by calculating what’s inside the parentheses: . Now, substitute that back into the expression: . Next, we square , which gives us . Finally, multiply that by : . So, the simplified expression equals approximately !

Now, here’s a fun tidbit: did you know that the order of operations is often remembered by the acronym PEMDAS? It stands for Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This handy mnemonic helps keep mathematical minds on the right track—no matter how wild the numbers get!

And speaking of numbers, if you ever want to explore the world of operations beyond the basics, diving into real-world applications can be enlightening! For example, order of operations is fundamental not just in mathematics class, but also in programming and computer algorithms. Understanding how to sequence operations correctly can optimize everything from basic calculations to complex simulations and data analysis in tech!
