InstaCalc makes your life easy. It’s a refreshingly different calculator that is simple, fast and surprisingly fun. Answers appear as you type. Normal calculators and spreadsheets make you type and press Enter. Change the numbers, press Enter. Change the numbers again, press Enter. You can try a demo at the end of this article.
You can see how you got an answer and change the numbers in real-time. You don’t have to switch between viewing a cell’s results and editing the details. Write what makes it easy for you, not the computer. Type 6.6 billion (or 6.6b), not 6600000000. Write “distance = mph * hours”, not “=E3 * C2”. Reference your results by name, not cell number.
You can share a link to any calculation – no logins, no attachments, no fuss. Readers can see your thoughts, change the numbers, and comment back with a new link!
The best part is that your original link stays the same. If someone changes the numbers, they get a new link when they save the page. Compare this to trying to post a spreadsheet or screenshot to your blog – link to a live, editable calculator.
