Understanding BIDMAS/BODMAS rules can be tricky for Year 9 students, especially when using them in real-life situations.
Let’s break it down with some examples:
Budgeting: Figuring out how much money you need can be a lot to handle. For instance, if you want to find out your total expenses (E) from different areas, you use this formula:
(E = (Rent + Utilities) \times (1 + Tax) - Discounts).
In this formula, the order of operations is really important. If you skip a step, you might end up with a big mistake in your budget!
Recipe Adjustments: Adjusting recipes, like when you want to double or cut a recipe in half, needs careful thinking about the order. If a recipe says you need (2 \times (3 + 4)) cups of flour, forgetting the parentheses might give you the wrong amount of flour.
Even though these concepts can be tough, practicing and paying attention to the order of steps can really help students get through these calculations successfully.
