This tool helps you simplify algebraic expressions by combining like terms efficiently.

## How to Use the Combining Like Terms Calculator

Enter a mathematical expression involving variables (like “3x + 2x – 4y + y”) into the provided input field. Click “Calculate” to combine like terms and simplify the expression.

## How It Calculates the Result

The script parses the expression to identify and group terms with the same variables. It then sums the coefficients of those like terms. The grouped and simplified terms are then displayed in simplified form.

## Limitations

The calculator assumes proper spacing and does not currently handle fractions or complex expressions that involve parentheses or exponents. Ensure all terms are separated by valid operators (+ or -) and that each term contains a clear variable portion.

## Use Cases for This Calculator

### Use Case 1: Adding like terms with positive coefficients

You have an expression like 2x + 3x – 5x. You want to combine the terms to simplify the expression by adding the coefficients of the like terms together. The calculator will help you quickly and accurately compute the result.

### Use Case 2: Combining like terms with negative coefficients

You encountered a problem with terms like -4y – 5y + 2y. By using the calculator, you can effortlessly add and subtract the coefficients of the terms to simplify the expression and obtain the correct result without any errors.

### Use Case 3: Including constants with like terms

In an equation such as 4a + 7 + 2a – 3, you need to combine the constants and the like terms together to simplify the expression. The calculator ensures you accurately handle the coefficients and constants to simplify the equation efficiently.

### Use Case 4: Handling multiple variables in like terms

You have an expression with multiple variables like 3x – 2y + 5x – 4y. By using the calculator, you can effortlessly deal with multiple variables and simplify the expression by combining the coefficients of the like terms accurately.

### Use Case 5: Simplifying expressions with exponents
