✅ What Does the Combine Like Terms Calculator Do?

The calculator takes an algebraic expression and simplifies it by:

Grouping similar variable terms (e.g., 3x+5x3x + 5x3x+5x)
Combining constants correctly
Handling positive and negative signs
Supporting expressions with exponents (e.g., x2x^2×2, y3y^3y3)
Displaying a simplified version of the expression
Showing detailed step-by-step working

✅ How to Use the Combine Like Terms Calculator

You don’t need any special knowledge to use the tool. Just follow these simple steps:

✔ Step 1: Enter Your Algebraic Expression

In the input field labeled “Enter algebraic expression”, type your expression.
Example:

3x + 5x - 2y + 7y + 10

✔ Step 2: Click the “Calculate” Button

After entering your expression, click the Calculate button. The calculator will:

Identify like terms
Combine them correctly
Display a simplified result
Show clear step-by-step explanation

✔ Step 3: View the Simplified Expression

The result will appear under “Simplified Expression:”
You can copy the output using the Copy button beside the result field.

✔ Step 4: Check the Step-by-step Solution

Below the result, the Step-by-step solution section explains exactly how the tool simplified your expression.

✔ Step 5: Reset if Needed

Click Reset to start fresh and enter a new expression.

✅ Practical Example

Let’s take a common algebraic expression:

Input:

4a + 7 - 2a + 3a - 5 + 6b - 4b

How the calculator processes it:

Groups like variable terms:
- 4a−2a+3a=5a4a – 2a + 3a = 5a4a−2a+3a=5a
- 6b−4b=2b6b – 4b = 2b6b−4b=2b
Combines constants:
- 7−5=27 – 5 = 27−5=2

Final Output:

5a + 2b + 2

You will also see each step listed clearly so you can understand the logic behind the simplification.
