Exemplars (from the NaCCA curriculum)
E.g. 1. Use the order of operations (BODMAS or PEDMAS) to simplify whole number expressions with more than two operations. PEDMAS is Parenthesis, Exponents, Multiply/Divide (going from left to right)and Add/subtract (going from left to right). i. 3 4 ÷ 3 2 + 40 - 2 3 × 3 2 ÷ 9 ii. 18 ÷ 6 × (4 - 3) + 6 iii. 18 ÷ 3 2 × (4 - 3) × 10 E.g. 2. Use the order of operations (BODMAS or PEDMAS) to simplify fractions with more than two operations. a) 2 × 3 - 5 ÷ 2 1 3 4 8 2 b) 3 ÷ 3 +( 4 - 1 ) 4 8 5 2 c) ( 3 + 5 ) × 4 - 1 4 8 11 2
