Combine Like Terms Calculator
Combining like terms is a fundamental skill in algebra that helps simplify expressions and solve equations more efficiently. Our Combine Like Terms Calculator is a handy tool designed to assist students, teachers, and anyone working with algebra by quickly simplifying expressions and clearly showing the step-by-step combination of terms.
What is the Combine Like Terms Calculator?
This calculator allows you to:
- Input any algebraic expression with variables and constants.
- Automatically identify and combine like terms.
- Simplify the expression by adding or subtracting coefficients of matching variables.
- Display the original expression alongside the simplified result.
- Provide a detailed breakdown of the terms combined for clarity.
Why Combine Like Terms?
When working with algebraic expressions, like terms are terms that contain the same variable(s) raised to the same power(s). Combining these terms:
- Simplifies expressions for easier manipulation.
- Helps in solving equations efficiently.
- Clarifies the structure of an expression.
- Reduces errors in algebraic calculations.
How to Use the Combine Like Terms Calculator

Step 2: Use Examples (Optional)
Try preset examples like:
2x + 3x + 54x - 2x + 3y - y5a + 2b - 3a + 4b + 6
Click on the example buttons to fill the input quickly.
Step 3: Click Calculate
The calculator will show:
- The original expression you entered.
- The simplified expression with like terms combined.
- The total number of terms combined.
- A breakdown showing how coefficients were added or subtracted for each variable and constants.
Step 4: Reset to Start Over

Example Usage
Suppose you enter the expression:3x + 5x - 2y + 7y + 4
After clicking Calculate, you get:
- Original Expression: 3x + 5x - 2y + 7y + 4
- Simplified Expression: + 8x + 5y + 4
- Terms Combined: 5 terms
- Breakdown:
- x: 3x + 5x = 8x
- y: -2y + 7y = 5y
- Constant: 4

Frequently Asked Questions (FAQs)
1. What are like terms?
Like terms have the same variable(s) raised to the same power(s) and can be combined by adding or subtracting their coefficients.
2. Can this calculator handle negative coefficients?
Yes, it correctly processes both positive and negative coefficients.
3. Does it work with multiple variables?
Absolutely! It combines terms separately for each variable.
4. How do I enter constants?
Simply type numbers without variables (e.g., +4 or -7). They will be combined separately.
5. Can I input decimals or fractions?
The calculator supports decimal numbers, but fractions should be converted to decimals first.
6. Will it reorder terms automatically?
Yes, the simplified expression is presented with combined terms properly ordered with signs.
7. What if all terms cancel out?
The result will show 0, indicating the expression simplifies completely.
8. Is this tool suitable for students?
Definitely, it’s designed to assist learners in understanding and practicing algebraic simplification.
9. Can I see how the terms were combined?
Yes, the breakdown section shows exactly how coefficients of each variable and constants are combined.
10. What if I enter an invalid expression?
The calculator will ignore invalid parts but works best with correctly formatted algebraic expressions.
