Order of Operations Calculator

How to Use This Calculator

1. Enter your mathematical expression in the input field. Use standard mathematical notation:
• Use parentheses/brackets ( ) [ ] { } to control the order of operations
• Use ^ for exponents (alternatively, you can use ** in the calculator)
• Use × for multiplication (alternatively, use *)
• Use ÷ for division (alternatively, use /)
• Enter addition and subtraction as usual
2. Click the "Calculate" button to evaluate your expression
3. The calculator will display the result following the standard order of operations (PEMDAS/BODMAS)
4. If you make a mistake, click "Reset" to clear the form and start over

Understanding the Order of Operations (PEMDAS/BODMAS)

The Order of Operations is a set of rules that determines the sequence in which operations should be performed in a mathematical expression to ensure a consistent result:

• P/Barentheses/Brackets: Solve expressions inside parentheses or brackets first
• E/OExponents/Orders: Calculate exponents or powers next
• M/DMultiplication and Division: Perform multiplication and division from left to right
• A/SAddition and Subtraction: Finally, perform addition and subtraction from left to right

Examples

Here are some example expressions you can try:

• "(3+5)×2^2-8÷4" should yield 18
• "(10-2)×3+4^2" should yield 38
• "15÷3×2+1-5" should yield 3
• "2^3+6×(1+2)" should yield 20

Limitations

This calculator supports basic mathematical operations and parentheses. It does not support:

• Advanced functions (trigonometry, logarithms, etc.)
• Complex numbers
• Variable assignments
