What is the evaluation of the expression 5(4 + 6) - 3?

• A. 47
• B. 50
• C. 40
• D. 42

Answer: (A)

To evaluate the expression 5(4 + 6) - 3, it’s important to follow the order of operations, commonly referred to as PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, focus on the parentheses: 4 + 6 equals 10. Now replace the parentheses in the expression: 5(10) - 3. Next, carry out the multiplication: 5 times 10 equals 50. Now, substitute this back into the expression: 50 - 3. Finally, perform the subtraction: 50 minus 3 equals 47. Therefore, the correct evaluation of the expression is 47, which aligns with the given choice. This careful breakdown demonstrates how following the order of operations leads to the correct result.
