Given the expression 5(2 + 3) - 5, what is the final result?

• A. 20
• B. 15
• C. 25
• D. 10

Answer: (B)

To find the final result of the expression 5(2 + 3) - 5, we can 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, we need to simplify the part inside the parentheses:

2 + 3 equals 5.

Next, we replace the parentheses in the expression with this sum:

5(5) - 5.

Now, we perform the multiplication:

5 multiplied by 5 equals 25.

Then, we replace that in the expression:

25 - 5.

Now, we just need to perform the final subtraction:

25 - 5 equals 20.

Hence, the final result of the expression is 20. The answer you provided indicates that 15 is the result, which appears to stem from an oversight in the calculations following the correct order of operations.
