Whether you’re cooking, tracking BMI, or planning a construction project, calculators will make your life easy. In this topic, we are going to talk about order of operations calculators.

What is an Order Of Operations Calculator?

An order of operations calculator is a tool that helps solve mathematical expressions by applying the correct sequence of operations. It follows the PEMDAS/BODMAS rule, which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This calculator ensures accuracy in solving expressions by adhering to these rules.

How to Use the Order Of Operations Calculator?

Given below is a step-by-step process on how to use the calculator:

Step 1: Enter the expression: Input the mathematical expression into the given field.

Step 2: Click on calculate: Click on the calculate button to solve the expression and get the result.

Step 3: View the result: The calculator will display the result instantly.

How to Solve Mathematical Expressions Using Order Of Operations?

In order to solve mathematical expressions, follow the PEMDAS/BODMAS rule.

1. Parentheses/Brackets: Solve expressions inside parentheses or brackets first.

2. Exponents/Orders: Calculate powers or roots.

3. Multiplication and Division: Perform these operations from left to right.

4. Addition and Subtraction: Finally, handle these operations from left to right. This sequence ensures the expression is solved correctly without errors.

Tips and Tricks for Using the Order Of Operations Calculator

When using an order of operations calculator, there are a few tips and tricks that can make it easier and help avoid mistakes:

Understand the order of operations thoroughly to recognize how expressions are evaluated.

Make sure to input expressions correctly, using parentheses to clarify the order of operations.

Check your work by solving the expression manually to confirm the calculator's output.

Common Mistakes and How to Avoid Them When Using the Order Of Operations Calculator

Even with a calculator, mistakes can happen. Here are some common mistakes and how to avoid them:

Problem 1

What is the result of 3 + 6 × (5 + 4) ÷ 3 - 7?

Okay, lets begin

First, calculate inside the parentheses: 5 + 4 = 9

Now the expression is: 3 + 6 × 9 ÷ 3 - 7

Perform multiplication and division from left to right: 6 × 9 = 54 54 ÷ 3 = 18

Now the expression is: 3 + 18 - 7

Perform addition and subtraction from left to right: 3 + 18 = 21 21 - 7 = 14

The result is 14.

Explanation

By following the order of operations, we solved the expression step by step, ensuring accuracy by performing operations in the correct sequence.

Problem 2

Calculate the result of 8 + (3 × (2 + 3²)) ÷ 2.

Okay, lets begin

First, resolve the exponent: 3² = 9

Now the expression inside the parentheses becomes: 2 + 9 = 11

Now the expression is: 8 + (3 × 11) ÷ 2

Perform the multiplication: 3 × 11 = 33

Now the expression is: 8 + 33 ÷ 2

Perform the division: 33 ÷ 2 = 16.5

Now the expression is: 8 + 16.5

Perform the addition: 8 + 16.5 = 24.5

The result is 24.5.

Explanation

By resolving the exponent first and following the order of operations, the expression was simplified step by step to reach the final answer.

Well explained 👍

Problem 3

Solve the expression 5 × (7 - 3) + 4² ÷ 2.

Okay, lets begin

First, solve inside the parentheses: 7 - 3 = 4

Now the expression is: 5 × 4 + 4² ÷ 2

Resolve the exponent: 4² = 16

Now the expression is: 5 × 4 + 16 ÷ 2

Perform multiplication and division from left to right: 5 × 4 = 20 16 ÷ 2 = 8

Now the expression is: 20 + 8

Perform the addition: 20 + 8 = 28 The result is 28.

Explanation

By following the correct sequence of operations, the expression is solved accurately, ensuring each step is followed correctly.

Well explained 👍

Problem 4

What is the result of (10 + 5) × (3² - 7)?

Okay, lets begin

First, calculate inside the parentheses: 10 + 5 = 15 3² = 9

Now the expression inside the parentheses becomes: 9 - 7 = 2

Now the expression is: 15 × 2

Perform the multiplication: 15 × 2 = 30

The result is 30.

Explanation

By solving each part of the expression according to the order of operations, the final result is obtained accurately.

Well explained 👍

Problem 5

Evaluate the expression 12 ÷ (2 + 4) × 3 - 1.

Okay, lets begin

First, solve inside the parentheses: 2 + 4 = 6

Now the expression is: 12 ÷ 6 × 3 - 1

Perform division and multiplication from left to right: 12 ÷ 6 = 2 2 × 3 = 6

Now the expression is: 6 - 1

Perform the subtraction: 6 - 1 = 5

The result is 5.

Explanation

By following the proper order, the operations are performed in sequence, ensuring an accurate final result.
