Calculators are reliable tools for solving simple mathematical problems and advanced calculations like trigonometry. 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.
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.
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.
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.
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.
Even with a calculator, mistakes can happen. Here are some common mistakes and how to avoid them:
What is the result of 3 + 6 × (5 + 4) ÷ 3 - 7?
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.
By following the order of operations, we solved the expression step by step, ensuring accuracy by performing operations in the correct sequence.
Calculate the result of 8 + (3 × (2 + 3²)) ÷ 2.
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.
By resolving the exponent first and following the order of operations, the expression was simplified step by step to reach the final answer.
Solve the expression 5 × (7 - 3) + 4² ÷ 2.
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.
By following the correct sequence of operations, the expression is solved accurately, ensuring each step is followed correctly.
What is the result of (10 + 5) × (3² - 7)?
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.
By solving each part of the expression according to the order of operations, the final result is obtained accurately.
Evaluate the expression 12 ÷ (2 + 4) × 3 - 1.
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.
By following the proper order, the operations are performed in sequence, ensuring an accurate final result.
