Understanding the Order of Operations
The Order of Operations is a crucial concept in mathematics that ensures consistent and unambiguous interpretation of expressions. It provides a set of rules to determine the priority in which different operations should be performed within an equation. By following the Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), one can solve complex mathematical problems accurately and avoid confusion.
A. Explanation of PEMDAS acronym
The acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. These operations must be performed in the specified order to obtain the correct solution.
The first priority is given to parentheses. If an equation contains parentheses, the expression inside them should be evaluated first. Parentheses allow the isolation and evaluation of specific parts of an equation, and their removal simplifies the problem.
B. Emphasize the significance of following this order
Following the Order of Operations is crucial because it ensures consistent and predictable outcomes when solving mathematical problems. Without adhering to this order, the solution to an equation may vary depending on the interpretation, leading to incorrect results.
By consistently applying the Order of Operations, mathematicians, scientists, and engineers can communicate and share their findings accurately. It also enables students to solve math problems step-by-step, building a solid foundation for more advanced mathematical concepts.
Understanding and correctly implementing the Order of Operations is necessary not only for academic purposes but also in everyday life. For example, when calculating bills or budgeting expenses, following the correct order ensures accurate calculations and prevents potentially costly errors.
In summary, understanding the Order of Operations is fundamental in solving mathematical problems correctly. Following the rules outlined by PEMDAS guarantees consistent results and builds a strong mathematical foundation. By mastering this concept, individuals can solve complex equations accurately and confidently navigate various real-life situations where mathematical calculations are required.
## Step 1: Identify & Eliminate Parentheses
### A. Explaining the absence of parentheses in the given problem
In the problem 10-10×10+10, there are no parentheses present. Parentheses are commonly used in mathematical expressions to indicate a different order of operations within a larger equation. In this case, the absence of parentheses simplifies the problem as it allows us to follow a more straightforward order of operations.
### B. Providing examples with parentheses to exhibit the process if they were present
To better understand the role of parentheses and their impact on the order of operations, let’s consider an example with parentheses. Suppose we have the expression: 10 – (2 + 3) x 2. In this case, the parentheses indicate that the addition operation should be performed before the multiplication.
To solve this example, we would start by evaluating the expression within the parentheses: 2 + 3 = 5.
Afterward, we proceed with the multiplication: 5 x 2 = 10.
Finally, we subtract 10 from the original number, 10, resulting in 0 as the final answer.
This example demonstrates how the presence of parentheses can alter the sequence of calculations. However, in the given problem of 10-10×10+10, there are no parentheses present. Therefore, we can move on to the next step of the order of operations.
By understanding the concept of parentheses and their effect on mathematical expressions, you will be better equipped to handle more complex problems involving multiple sets of parentheses. However, in this particular case, the absence of parentheses simplifies the calculations, making it easier to proceed to the following steps of the order of operations.
Remember, when working with expressions that contain parentheses, it is crucial to always evaluate the operations within the parentheses first, before moving on to other parts of the equation. Without parentheses present, we can focus on the next step in solving the problem: evaluating exponents.
IStep 2: Evaluate Exponents
Explanation of Exponents
Exponents are a way to represent repeated multiplication. An exponent is a small number written above and to the right of a number, called a base, and it indicates how many times the base should be multiplied by itself.
For example, in the expression 2^3, the base is 2 and the exponent is 3. This means that 2 should be multiplied by itself 3 times: 2 x 2 x 2 = 8.
Example:
If we had the expression 5^2, the base is 5 and the exponent is 2. Therefore, we need to multiply 5 by itself 2 times, resulting in 5 x 5 = 25.
It is important to note that the given problem, 10-10×10+10, does not contain any exponents. Exponents are not a part of this expression, so we can move on to the next step in solving it.
Step 3 – Perform Multiplication and Division, from left to right
A. Explanation of the multiplication and division rules
In order to correctly solve mathematical expressions, it is crucial to understand the rules for multiplication and division. These operations should be performed from left to right, meaning that the calculations should be carried out in the order they appear in the expression. Multiplication is denoted by the symbol “*”, while division is denoted by “/”.
B. Walking through the calculations and providing the correct answer
Now that we have successfully eliminated parentheses and assessed any exponents in the given expression “10-10×10+10,” it is time to move on to the next step: performing multiplication and division.
Following the order of operations, we first look for any multiplication or division operations from left to right. In this case, we have one multiplication operation: 10 multiplied by 10.
10 x 10 = 100
Now that we have performed the multiplication, we rewrite the expression using the calculated value:
10 – 100 + 10
Moving on, we need to perform the remaining addition and subtraction operations from left to right.
10 – 100 = -90
Now, we rewrite the expression using the intermediate result:
-90 + 10
Finally, we perform the addition:
-90 + 10 = -80
Therefore, the correct solution for the expression 10-10×10+10 is -80.
It is important to note that in cases where there are multiple multiplication or division operations, performing them from left to right ensures that we obtain the correct result. Failing to follow this order may lead to errors and incorrect solutions.
By applying the multiplication and division rules correctly, we have successfully solved the given expression. Moving forward, we will now proceed to the next step: performing addition and subtraction.
Step 4: Perform Addition and Subtraction, from left to right
A. Clarification of the addition and subtraction rules
In this step, we will focus on performing addition and subtraction operations from left to right. It is important to note that addition and subtraction have the same precedence and should be done in the order they appear.
When performing addition, we simply combine two or more numbers to obtain a single sum. For example, 5 + 3 equals 8. Addition is commutative, meaning that the order of the numbers does not affect the result. Therefore, 3 + 5 also equals 8.
Subtraction, on the other hand, involves subtracting a number from another. For instance, when subtracting 3 from 7, we get 4. Unlike addition, subtraction is not commutative. In other words, the order of the numbers does matter. For example, 7 – 3 is not the same as 3 – 7.
B. Executing the operations to obtain the final result
In our problem, 10 – 10 × 10 + 10, we will perform the operations in the order they appear from left to right.
First, we start with 10 – 10, which equals 0. Next, we multiply 0 by 10, resulting in 0. Finally, we add 10 to 0, giving us a final answer of 10.
To summarize, the correct solution to the problem 10 – 10 × 10 + 10 is 10. It is essential to follow the order of operations and perform addition and subtraction operations in the order they appear to arrive at the right result.
It is worth noting that many people make the mistake of performing addition and subtraction before multiplication and division, which leads to incorrect results. By understanding and applying the order of operations correctly, you can avoid such errors and solve mathematical problems accurately.
Remember to take your time, double-check each step, and follow the order of operations diligently. Practice solving similar problems to reinforce your understanding of this fundamental concept in mathematics.

Multiplication involves multiplying two numbers together, while division involves dividing one number by another. To illustrate this step, let’s consider a similar example with parentheses: (2+3) x 4 ÷ 2.
First, we solve the expression inside the parentheses, which evaluates to 5. Then, we proceed with the multiplication and division from left to right.
(2+3) x 4 ÷ 2 = 5 x 4 ÷ 2
= 20 ÷ 2
= 10
In the original problem, we have 10-10×10+10. Following the same principle, we complete the multiplication before moving on to the next step.
10-10×10+10 = 10 – 100 + 10
Addition and Subtraction
Finally, the last step is to perform addition and subtraction from left to right.
Using the result from the previous step, we continue with the addition and subtraction:
10 – 100 + 10 = -90 + 10 = -80
By following the order of operations correctly, we find that the value of 10-10×10+10 is -80.
To summarize, applying the order of operations (PEMDAS) to the original problem involves performing multiplication and division from left to right, followed by addition and subtraction from left to right.
Remembering and applying these rules correctly is crucial to solving mathematical problems accurately and consistently.
