Introduction to the order of operations

How would you solve this problem?

12 - 2 ⋅ 5 + 1

The answer you get will depend largely on the order in which you solve the problem. For example, if you work the problem from left to right -12-2, then 10⋅5, then add 1-you'll get 51.

On the other hand, if you solve the problem in the opposite direction-from right to left -the answer will be 0.

Finally, what if you did the math in a slightly different order? If you multiply first, then add, the answer is 3.

It turns out that 3 actually is the correct answer because it's the answer you get when you follow the standard order of operations. The order of operations is a rule that tells you the right order in which to solve different parts of a math problem. ( Operation is just another way of saying calculation. Subtraction, multiplication, and division are all examples of operations.)

The order of operations is important because it guarantees that people can all read and solve a problem in the same way. Without a standard order of operations, formulas for real-world calculations in finance and science would be pretty useless-and it would be difficult to know if you were getting the right answer on a math test!

Using the order of operations
The standard order of operations is:

1. Parentheses

2. Exponents

3. Multiplication and division

4. Addition and subtraction

In other words, in any math problem you must start by calculating the parentheses first, then the exponents, then multiplication and division, then addition and subtraction. For operations on the same level, solve from left to right. For instance, if your problem contains more than one exponent, you'd solve the leftmost one first, then work right.

Let's look at the order of operations more closely and try another problem. This one might look complicated, but it's mainly simple arithmetic. You can solve it using the order of operations and some skills you already have.

4 / 2 ⋅ 3 + (4 + 6 ⋅ 2) + 18 / 3 ² - 8

Parentheses

Always start with operations contained within parentheses. Parentheses are used to group parts of an expression.

If there is more than one set of parentheses, first solve for the ones on the left. In this problem, we only have one set:

In any parentheses, you follow the order of operations just like you do with any other part of a math problem.

Here, we have two operations: addition and multiplication. Because multiplication always comes first, we'll start by multiplying 6 ⋅ 2 .

4+12 is 16. So we've simplified our parentheses to 16. Since we just have a single number in the parentheses, we can get rid of them all together-they're not grouping together anything now.

Exponents

Second, solve any exponents. Exponents are a way of multiplying a number by itself. For instance, 2 ³ is 2 multiplied by itself three times, so you would solve it by multiplying 2⋅2⋅2. (To learn more about exponents, review our lesson here).

There's only one exponent in this problem. 3 ² is 3 multiplied by itself twice-in other words, 3 ⋅ 3.

4 / 2 ⋅ 3 + 16 + 18 / 9 - 8

Multiplication and division

Next, look for any multiplication or division operations. Remember, multiplication doesn't necessarily come before division-instead, these operations are solved from left to right.

Starting from the left means that we need to solve 4 / 2 first.

4 / 2 ⋅ 3 + 16 + 18 / 9 - 8

4 divided by 2 is 2. That makes our next problem 2 ⋅ 3.

2 ⋅ 3 is 6. Finally, there's only one multiplication or division problem left: 18 / 9.

18 / 9 is 2. There's nothing left to multiply or divide, so we can move on to the next and final part of the Order of Operations: addition and subtraction.

Addition and subtraction

Our problem looks a lot simpler to solve now. All that's left is addition and subtraction.

Just like we did with multiplication and division, we'll add and subtract from left to right. That means that first we'll add 6 and 16.

22 + 2 is 24. Only one operation left: 24 - 8.

We're done! We've solved the entire problem, and the answer is 16. In other words, 4 / 2 ⋅ 3 + ( 4 + 6 ⋅ 2 ) + 18 / 32 - 8 equals 16.

Whew! That was a lot to say, but once we broke it down into the right order it really wasn't that complicated to solve. When you're first learning the order of operations, it might take you a while to solve a problem like this. With enough practice, though, you'll get used to solving problems in the right order.

Remembering the order of operations

If you use it a lot, you'll eventually get the hang of the order of operations. Until then, it can be helpful to use a word or phrase to remember it. Two popular ones are the nonsense word PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) and the phrase Please Excuse My Dear Aunt Sally.

When solving an , a set of guidelines known as the order of operations must be followed. When we use the word "operations" in math, we refer to the process of evaluating any mathematical expression, which includes arithmetic operations like addition, subtraction, multiplication, and division. In this article, we explain the rules governing the order of operations in detail and provide some examples.

What is the order of operations?

In arithmetic, evaluating a math expression may require us to perform numerous mathematical operations, and achieve several outcomes by simplifying the answer. For every kind of expression, there can only be one right response.

We use a set of rules to simplify any given mathematical phrase in order to find the correct answer. All of the fundamental mathematical operators are based on these rules: Addition (+), subtraction (-), division ( ÷ ), and multiplication (x) are examples of operators.

BIDMAS is key to the order of operations. It stands for:

When faced with an equation, start solving from the top (brackets) and working your way down to subtraction.
How to solve a problem in mathematics
Why is the order of operations important?

A mathematical problem's various components should be solved in a specific order according to the order of operations. Calculation is just another word for operation. Examples of operations include addition, subtraction, multiplication, and division.

The importance of the order of operations stems from the fact that it ensures that everyone can understand and approach a mathematical problem the same way to arrive at the right answer. Formulas for actual calculations in science and finance would be quite worthless without a set order of operations, and it would be challenging to determine whether your response on a math test was correct.

The order of operations in mathematics helps determine the right value for an equation. By way of analogy, the order of events plays a role in daily life as well. For instance, it will be difficult to get dressed if you put on your shoes before your pants. Similarly, if you don't follow the correct procedure while cooking, the result will be a kitchen disaster.

Ways to Remember Order of Operations

BIDMAS, PEMDAS, and BODMAS are three distinct words that all mean the same thing. You may get mixed up so try remembering them with a pneumonic. For example, the phrase "Please Excuse My Dear Aunt Sally" is a reminder of PEMDAS.

It stands for "Parentheses, Exponents, Multiplication, Division, Addition, Subtraction". Similarly, by using the word BODMAS, we can recall the sequence of events (Brackets, Orders, Division, Multiplication, Addition, and Subtraction).
Implementing the suggested actions is the simplest approach to learn the order of operations:

First begin by condensing terms inside the brackets.

Then put the exponential terms to use.

or multiplication should come next.

Conclude by counting, deducting, or adding.

How to multiply decimals
How to follow the order of operations in mathematics

Take note of the expression. The first rule is to solve the numbers that are enclosed in brackets or parentheses. We resolve grouping operations from the inside out. There is a certain way to solve the parenthesis, i.e., [ () ], therefore take note of the pattern of brackets that are present in the phrase.

First, solve the round brackets (), then the curly brackets { }, then the box brackets [ ]. What this means is that whatever equation is within the brackets, you solve that first before anything else.

Search for and solve any number that is present in the form of exponents after solving the numbers in the parenthesis.

We are now down to the fundamental four operators. Find the numbers that have been multiplied or divided, and then solve them from left to right.

Finally, search for terms with addition or subtraction and work your way right to left.

Examples of order of operations

To understand the rules used in the order of operations, let's take a look at some practical examples.

Our answer is 50 but what would have happened if we hadn't followed the order of operations?
2 + 4 x 12 = 72
72 is the wrong answer, and by a large amount. This shows the importance of following the order of operations.

4 x 7 = 28 is the correct answer.

If we hadn't followed the order of operations, we would have gotten an answer of 22 which is, again, off target.

Then we can multiply.

This is a complex one so you may be unsure where to begin. Nevertheless, using BIDMAS you will find the right answer.
