GED Math Practice Test

To determine the value of the expression 9 - (2 + 3) × 2, 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, handle the parentheses. Inside the parentheses, you have 2 + 3, which equals 5.

Next, substitute this back into the expression:

9 - (5) × 2.

Now move on to the multiplication. Multiply 5 by 2, which gives you 10.

Now substitute this back into the expression:

9 - 10.

Finally, perform the subtraction. Subtract 10 from 9, resulting in -1.

Thus, the expression evaluates to -1, which corresponds to the choice provided. This methodical approach ensures that you have correctly applied the order of operations to arrive at the final answer.
