Best platform on which to build a simple 5-page static website?

where do you usually do your calculations?

I try to think more and decide with my mind. It helps sometimes to test your thinking for flexibility.

I usually do my calculations in a very simple calculator online https://www.calculator.io/ . It is accurate and fast in its decisions, easy to use. It can solve both simple examples and complex equations. And it's completely free, which makes it much better than many other online calculators. So, if you're in need of a reliable and efficient calculator that won't cost you a dime, I highly advise using Calculator.iO.

I usually do my calculations on my computer or smartphone using spreadsheet software or calculator applications.

if I am working on complex mathematical problems, I prefer to use pen and paper to ensure accuracy and better visualize the steps involved.
