Step 1: Evaluate the innermost parentheses. According to BODMAS, we start with the operations inside the innermost brackets. The innermost bracket is (20 - 10 ÷ 2). Inside this, division takes precedence over subtraction. 10 ÷ 2 = 5 So, the expression inside the parentheses becomes: 20 - 5 = 15 The original expression now simplifies to: 100 - [60 - \30 + 15\] Step 2: Evaluate the curly braces. Next, we evaluate the expression inside the curly braces: \30 + 15\. 30 + 15 = 45 The expression now simplifies to: 100 - [60 - 45] Step 3: Evaluate the square brackets. Now, we evaluate the expression inside the square brackets: [60 - 45]. 60 - 45 = 15 The expression now simplifies to: 100 - 15 Step 4: Perform the final subtraction. 100 - 15 = 85 The evaluated expression is 85.
