evaluate -1 (2) (-5)
When evaluating the expression -1 (2) (-5), we will follow the order of operations, also known as PEMDAS.
First, we will perform the multiplication inside the parentheses from left to right:
2 * (-5) = -10
Now, we have -1 * (-10) left, which is equal to:
-1 * (-10) = 10
Therefore, the value of the expression -1 (2) (-5) is 10.
To evaluate the expression -1(2)(-5), we will follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Start with the innermost parentheses. In this case, we have -1 multiplied by 2.
-1 * 2 = -2
Step 2: Multiply the result from Step 1 by -5.
-2 * -5 = 10
Therefore, the value of -1(2)(-5) is 10.
To evaluate the expression -1(2)(-5), we follow the order of operations, which is parentheses, exponents, multiplication/division (from left to right), and finally addition/subtraction (from left to right).
First, we deal with the parentheses. Inside the parentheses, we have (-1) multiplied by (2)(-5).
Next, we perform the operations in the parentheses from left to right. We can multiply 2 by -5 first.
(-1)(2)(-5) = (-1)(-10)
Now, we multiply -1 by -10. The product of two negative numbers is positive.
(-1)(-10) = 10
Therefore, the expression -1(2)(-5) evaluates to 10.
