Evaluate 5 (-1) (4) (-1)
When calculating the expression 5 (-1) (4) (-1), we follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right).
First, we deal with the multiplication inside the parentheses: (-1) (4) = -4.
Now we have the expression 5 (-4) (-1).
Next, we multiply: 5(-4)(-1) = -20(-1).
Lastly, we multiply: -20(-1) = 20.
Therefore, 5 (-1) (4) (-1) equals 20.
To evaluate this expression, you need to follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
The expression you provided is 5 * (-1) * (4) * (-1). Let's break it down step by step:
1. Start with the multiplication: 5 * (-1) = -5
Now, we have: (-5) * (4) * (-1)
2. Continue with the next multiplication: (-5) * (4) = -20
Now, we have: (-20) * (-1)
3. Finally, perform the last multiplication: (-20) * (-1) = 20
Therefore, the value of 5 (-1) (4) (-1) is 20.
To evaluate the given expression 5(-1)(4)(-1), follow these steps:
Step 1: Start by multiplying the two negative numbers (-1)(-1). The product of two negative numbers is positive, so (-1)(-1) = 1.
Step 2: Now, multiply the two positive numbers (5)(4). The product of 5 and 4 is 20.
Step 3: Multiply the results from Step 1 and Step 2 together: 1 * 20 = 20.
Therefore, 5(-1)(4)(-1) evaluates to 20.
