What is the value of 15 - 4(2 + 3)?

To find the value of the expression 15 - 4(2 + 3), you need 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, solve the expression inside the parentheses: 2 + 3 equals 5.

Next, multiply this result by 4: 4 * 5 equals 20.

Now, substitute this back into the original expression: 15 - 20.

Finally, perform the subtraction: 15 - 20 equals -5.

Thus, the value of the expression is -5, which corresponds to the first choice. This systematic approach demonstrates how applying the order of operations accurately leads to the correct solution.
