Simplify the expression (8•5)•1
Does the dot mean multiply?
Yes
To simplify the expression (8•5)•1, we need to follow the order of operations, commonly referred to as PEMDAS:
1. Parentheses: Evaluate any operations within parentheses first. However, in this case, there are no parentheses.
2. Exponents: Simplify any exponents, but again, there are no exponents in this expression.
3. Multiplication and Division: Perform any multiplication or division from left to right. In this case, we have (8•5)•1. We can start by multiplying 8 and 5:
8•5 = 40
So, now we have 40•1.
4. Addition and Subtraction: Finally, perform any addition or subtraction from left to right. But since there are no addition or subtraction operations, we can skip this step.
Therefore, the simplified expression is simply 40.
