Teach me how to build a basic calculator for my shopify website

For this project, I need someone to teach me how to build a basic calculator for my shopify website. The calculator needs to have help and support features, and be embedded on the page. The language that the calculator needs to be built in is open to the freelancer’s discretion. I am looking for someone who has experience building calculators, who can help me understand how to configure the calculator and make it look nice on my shopify website. If you feel that you have the skills and experience necessary to take on this project, please reach out so we can get started. Thank you for considering this project!
