After incorporating feedback, I have some great new features for you to try out:

1. Use spaces in variable names

This was a biggie — I hated writing underscores between variables, and I’m sure you did too. Try this instead:

Wow! Use real, readable variables like “net sales” and “net cost”. I don’t know of any other programming languages that let you do this . We’ve come a long way from using “=E2 - C3″ in spreadsheet land.

2. Write equations in any order

Computers think linearly, but we don’t. Previously I required you to set your variables before they were used — no more! Put ‘em in any order you like:

How does Instacalc know what to do? Magic mind-reading fairies.

3. Use unicode variable names

For the international crowd, feel free to use all the accents and special characters you like:

And yep, you can use spaces in your unicode variable names also.

More feedback the merrier

I want to make InstaCalc easier and easier to use by eliminating the common headaches we face when solving problems. These features were the direct result of your feedback, so thank you! Your suggestions help improve the site for everyone, so keep it coming!

PS. I’ve received some suggestions about date & time calculations, which I’m looking into — stay tuned
