What is the result of simplifying the expression 90 - 60 / 30 + 10?

• A. 88
• B. 92
• C. 98
• D. 100

Answer: (C)

To simplify the expression 90 - 60 / 30 + 10, it’s essential to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). 1. Start with the division. In the expression, you need to perform \(60 / 30\) first. This simplifies to 2. 2. Now substitute back into the expression: \(90 - 2 + 10\). 3. Next, handle the subtraction and addition from left to right. Start with \(90 - 2\), which equals 88. 4. Finally, add 10 to 88, resulting in \(88 + 10 = 98\). Thus, the simplified result of the entire expression is 98, making it the correct answer.
