Answer:
³¹/₂
Step-by-step explanation:
This is an exercise in PEMDAS, the order of arithmetic operations:
parentheses > exponents > multiplication and division > addition and subtraction.
7 + 5 × (¼)2 - 6 ÷ (2 - 3)
Parentheses: = 7 + 5 × (¼)2 - 6 ÷ (-1)
Multiplication: = 7 + ⁵/₂ - 6/(-1)
Division: = 7 + ⁵/₂ - (-6)
Addition: = ¹⁹/₂ - (-6)
Subtraction: = ¹⁹/₂ + 6
Addition: = ³¹/₂
