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

The correct answer is: 98

To simplify the expression 90 - 60 / 30 + 10, it's important 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)). First, address the division in the expression. 1. Calculate 60 divided by 30, which equals 2. 2. Next, substitute this value back into the expression, giving us: 90 - 2 + 10. 3. Now, carry out the subtraction: 90 - 2 equals 88. 4. Finally, add 10 to 88, resulting in 98. Thus, simplifying the expression leads to the final answer of 98, confirming its correctness within the context of the order of operations applied.
