Following BODMAS/PEMDAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction): 1. 5 ÷ 5 + 5 ÷ 5 of 5 – 5 + 5 – 5 2. "Of": 5 of 5 = 5 * 5 = 25. The expression becomes: 5 ÷ 5 + 5 ÷ 25 – 5 + 5 – 5 3. Division: 5 ÷ 5 + 5 ÷ 25 – 5 + 5 – 5 4. Multiplication (None in this case). 5. Addition/Subtraction (left to right): 1 + 1/5 - 5 + 5 - 5 = 1 + 0.2 - 5 + 5 - 5. The result is: 1 + 0.2 - 5 + 5 - 5 = -3.8. The result is -3.8. Since this is not options 1, 2, or 3, the answer is None of these (4).
