Understanding BIDMAS/BODMAS: A Key to Success in Math

Learning BIDMAS/BODMAS has changed the way I do math in Year 9, especially when it comes to tricky number problems. If you’re not sure what BIDMAS means, it stands for:

• Brackets
• Indices (which are powers like squared or cubed)
• Division and Multiplication (from left to right)
• Addition and Subtraction (from left to right)

Knowing this order helps me solve problems the right way. Here’s how it has made a big difference for me:

1. Break Down Complex Problems

When I see a hard equation, like $3 + 4 \times (2^2 - 1)$, BIDMAS helps me break it into smaller pieces:

• Step 1: Do the brackets first: $2^2 - 1 = 3$.
• Step 2: Then, do the multiplication: $4 \times 3 = 12$.
• Step 3: Finally, do the addition: $3 + 12 = 15$.

Following these steps makes it easier and helps me avoid mistakes.

2. Minimize Mistakes

Before I learned about BIDMAS, I often messed up the order of operations, which led to wrong answers. For example, I sometimes added before multiplying when I shouldn’t have. Now, I feel more sure of myself because I know exactly what to do first!

3. Enhance Logical Thinking

Using BIDMAS also helps me think more logically. I can see how switching the order of operations changes the results. This skill is important not just in math but also in daily life. Whenever I hear someone say “calculate,” I think about the order of operations right away.

4. Build a Strong Foundation

Getting good at BIDMAS has given me a solid base for future math topics like algebra and calculus. The better I understand these rules now, the easier it will be to tackle tougher math later on.

In summary, understanding BIDMAS/BODMAS is not just about finding the right answers. It’s about creating a clear way to think. It helps me break down problems, make fewer mistakes, and get ready for more challenging math. So, if you’re in Year 9, make sure to learn these rules—you’ll be glad you did!
