How can I scrape Calculator tool site?

Hello everyone,
At the present, I want to scrape a Calculator tool site. But I don't know if Web Scraper is possible. And if it can do, How? Should I scrape by Element or html?

For example site: Free Online Calculators - Math, Fitness, Finance, Science. I just want to scrape that calculator tool.

Thanks for help!

I think there is no way WebScraper can assist you to "scrape" that Calculator.... You don't understand what scripts are, not html code.... Perhaps you can download all script together and try to create a new page... But suppose that is not ab issue of this tool...
There are many different scripts of analogs in internet... try to search for some of them....
