What is the result of evaluating -9p - 17 - 10?
To evaluate the expression -9p - 17 - 10, we need to follow the order of operations, which is commonly remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the expression step by step:
1. First, we need to simplify any parentheses or brackets, but there are none in this expression.
2. Next, we perform any exponentiation. Again, there are no exponents in this expression.
3. Moving on to multiplication and division, we multiply -9 with p. Multiplying a number by p simply means to combine them together, so the result is -9p.
4. Now we have -9p - 17 - 10. We can combine the -17 and -10 by adding them together, which gives us -27.
5. Finally, we subtract -27 from -9p by changing the sign and adding. Subtracting a negative number is the same as adding its positive counterpart. So, -9p - (-27) becomes -9p + 27.
Therefore, the final result of evaluating the expression -9p - 17 - 10 is -9p + 27.
