Thank you bobpursley and Ms. Sue
To find the value of the expression 16/2 + 2 × 5 - 3, we need to follow the order of operations. The order of operations is a set of rules that tells us which mathematical operations to perform first.
The acronym for the order of operations is PEMDAS, which stands for:
P: Parentheses (simplify expressions inside parentheses first)
E: Exponents (simplify any operations involving exponents or powers)
MD: Multiplication and Division (perform any multiplication or division operations from left to right)
AS: Addition and Subtraction (perform any addition or subtraction operations from left to right)
In this expression, we have the following operations:
1. Division: 16 ÷ 2 = 8
2. Multiplication: 2 × 5 = 10
3. Addition and Subtraction: 8 + 10 - 3 = 15
Therefore, the value of the expression 16/2 + 2 × 5 - 3 is 15.
So, the correct answer is B) 15.
