Use the order of operations to simplify 8 + 7 • 6 - 3 • 4 + 6 • 7
To simplify this expression using the order of operations, we follow the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
First, we handle the multiplication and division from left to right:
8 + 7 • 6 - 3 • 4 + 6 • 7
= 8 + 42 - 3 • 4 + 6 • 7
= 8 + 42 - 12 + 6 • 7
Next, we perform the remaining multiplication:
= 8 + 42 - 12 + 42
After that, we do the addition and subtraction from left to right:
= 50 - 12 + 42
= 38 + 42
= 80
Therefore, 8 + 7 • 6 - 3 • 4 + 6 • 7 simplifies to 80.
