What is the simplified form of the expression 4(2 + 3) - 5?

To simplify the expression 4(2 + 3) - 5, it is 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)).

First, deal with the parentheses. Inside the parentheses, you have 2 + 3, which simplifies to 5. This gives you the expression:

4(5) - 5.

Next, perform the multiplication. Multiply 4 by 5 to get 20:

20 - 5.

Finally, subtract 5 from 20, resulting in 15. Therefore, the simplified form of the expression is 15.

This serves as a clear demonstration of the importance of adhering to proper mathematical protocols during simplification.
