Replace letters with symbols (A=+, B=×, C=÷, D=-) and apply BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction) sequentially.
Replace letters with symbols (A=+, B=×, C=÷, D=-) and apply BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction) sequentially.
Substitute Symbols
Replace A with +, B with ×, C with ÷, and D with - to get: 14 + 2 × 6 - 20 ÷ 5
Apply BODMAS Rule
Follow order of operations: First perform division (20 ÷ 5 = 4), then multiplication (2 × 6 = 12), resulting in 14 + 12 - 4
Final Calculation
Perform addition and subtraction: 14 + 12 = 26, then 26 - 4 = 22.
A: 30 is incorrect as it ignores BODMAS order; B: 25 is incorrect arithmetic; C: 28 is incorrect arithmetic.
D is correct because following the BODMAS rule leads to 14 + 12 - 4 = 22.
Always perform division and multiplication before addition and subtraction to avoid common errors in these simplification problems.
