Understanding BODMAS/BIDMAS is really important for getting good at algebra, especially for Year 8 students.

BODMAS stands for:

• Brackets
• Orders (or Indices)
• Division and
• Multiplication (from left to right)
• Addition and
• Subtraction (from left to right)

This rule helps us figure out the right order to solve math problems.

Let’s look at the expression:

3 + 4 × 2.

If we didn’t use BODMAS, someone might just add first and think:

3 + 4 = 7,

then multiply:

7 × 2 = 14.

But according to BODMAS, we should do multiplication first:

4 × 2 = 8.

Now, we can add:

3 + 8 = 11.

So, the right answer is 11.

Knowing the BODMAS order helps you not make silly mistakes. It also makes you better at solving problems.

BODMAS/BIDMAS also helps a lot with more complicated expressions.

For example, let’s take a look at this expression:

2(3 + 5) - 4² ÷ 2.

Here’s how we can solve it step by step:

1. Brackets:
   • 3 + 5 = 8
2. Orders:
   • 4² = 16
3. Multiplication/Division:
   • 16 ÷ 2 = 8
4. Final Expression:
   • 2 × 8 - 8 = 16 - 8 = 8

By using BODMAS/BIDMAS, you can improve your algebra skills. It helps you understand math problems better and do calculations more accurately.

When you know how to use BODMAS, you’ll have a solid way to tackle tough problems. This skill is really important for doing well in math and will help you as you learn more advanced topics in the future.
