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
