Example Question #38 : Order Of Operations
Solve:
Following the order of operations, we can simplify this expression.
Recall the order of operations:
PEMDAS
Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. Perform these operations from left to right.
Example Question #38 : Order Of Operations
Evaluate the expression and solve for x:
In order to find the solutions for x, you first need to simplify the equation and properly use the order of operations. The order of operations is PEMDAS- Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
In this equation:
you have to do 
Secondly,
You are left with 
After you have simplified the equation, you can factor the equation.
Therefore the solutions are 
Example Question #41 : Order Of Operations
Solve:
Following the order of operations, we can go through these steps to solve the problem:
Example Question #42 : Order Of Operations
Find the value of the expression:
We need to use PEMDAS (Parentheses, Exponents, Multiplication, Divison, Addition, and Subtraction) to start and simplify this expression.
Step 1:
We will first do the operations in the parentheses:
Step 2:
We will then calculate the exponent. Be aware that the minus sign between the parentheses and the 2 does not effect the base of the exponent.
So, 
Step 3: We will now write the new equation based on the numbers that we got.
The new equation is: 
Step 4: Subtract 4 and 8.
Step 5: Add 6 to the result of the last operation.
Example Question #41 : Order Of Operations
Solve:
To solve this problem, we want to use the Order of Operations (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
First, we'll simplify what's inside the parentheses.
Next, we'll do multiplication and division as they appear from left to right.
Then, finally, we'll subtract.
Example Question #42 : Order Of Operations
Solve:
None of the given answers.
To solve this, we need to follow the Order of Operations (PEMDAS). To do this, we need to solve our exponential term first, then multiplication, then addition, like so:
Example Question #43 : Order Of Operations
Solve:
In PEMDAS, division and multiplication comes before addition and subtraction. Therefore,
Example Question #43 : Order Of Operations
Solve:
In PEMDAS, we apply the exponents first followed by multiplication and then finally subtraction.
Therefore,
Example Question #41 : Order Of Operations
Solve:
In PEMDAS, we do parentheses first, followed by multiplication and finally addition from left to right.
Therefore,
Example Question #43 : Order Of Operations
Solve:
In PEMDAS, we will apply the parentheses from left to right. Then we apply the exponent and addition inside the parentheses. Finally, we do division.
Therefore,
