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), Add/Subtract (going from left to right). i. 21 ÷ 3 + (3 × 9) × 9 + 5 ii. 18 ÷ 6 × (4 - 3) + 6 iii. 3 4 ÷ 9 + 40 - 2 3 × 3 2 ÷ 9 E.g. 2. Use the order of operations (BODMAS or PEDMAS) to simplify whole number expressions with more than two operations. a) 3 + 5 × 4 - 1 4 8 5 6 b) 3 ÷ 3 +( 4 - 1 ) 4 8 5 2 c) ( 3 + 5 ) × 4 - 1 4 8 11 2
