TGTET Paper 1 Exam 23 Jul 2017 Paper

Concept:Order of Operations (BODMAS/PEMDAS) for simplifying mathematical expressions.Explanation:To solve this, we follow the BODMAS rule, which stands for Brackets, Orders (powers and roots), Division and Multiplication (from left to right), Addition and Subtraction (from left to right).Step 1: Simplify the expression inside the innermost bracket first.We have $48 ÷ 6 + 4 × 3 - (-6)$.First, perform division and multiplication: $48 ÷ 6 = 8$ and $4 × 3 = 12$.So, the expression becomes $8 + 12 - (-6)$.Next, handle the subtraction of a negative number, which is equivalent to addition: $-(-6) = +6$.The expression is now $8 + 12 + 6$.Perform addition: $8 + 12 = 20$, and $20 + 6 = 26$.So, the value inside the curly bracket is $26$.Step 2: Now substitute this value back into the main expression.We have $[124 - {26}]$.Step 3: Perform the subtraction.$124 - 26 = 98$.Answer:98The correct option is C.
