Australian Curriculum Version 9 Says:
Find unknown values in numerical equations involving brackets and combinations of arithmetic operations, using the properties of numbers and operations.
What this means
Tip
Apply the rule of order when performing calculations involving a mix of operations. The agreed order is as follows:
- Calculations inside brackets are performed first.
- Indices or powers are performed next e.g., 42
- Multiplication and division are equally powerful operations performed left to right as they appear in a number sentence.
- Calculate addition and subtraction from left to right. For example, to calculate 10 – 2 + 3 you subtract first. This makes 8 + 3 = 11. The most common error is calculating the 2 + 3 first, then incorrectly thinking the number sentence is 10 – 5, which it is not.
- Caution: Students are often taught rules like BIMDAS, BOMDAS and PEDMAS, but some students think as a result that multiplication is given priority over division or addition is given priority over subtraction, neither of which is true.
