1. Educational Purposes Only

FOIL Calculator and all content on foilcalculator.com - calculators, step-by-step solutions, examples, and blog articles - are provided for general educational purposes. They are meant to help you learn and practice algebra, not to replace instruction from a teacher, tutor, or textbook.

2. Verify Your Results

We work hard to make every calculator and worked example correct, but software and content can contain errors. Always check important results yourself, for example by multiplying your answer back out or substituting a value such as x = 1, and follow your teacher's or exam board's methods and notation.

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, completeness, or fitness for a particular purpose. To the extent permitted by law, FOIL Calculator is not liable for any loss or damage arising from your use of, or reliance on, the Service - including grades, test results, or decisions based on its output.
