4.5 stars just for the lack of information, but long story short, after searching and trying i found that the expression has to be declared as if it was for JS, go to https://mathjs.org to watch examples on how to declare expressions, the page even has a box for testing the expressions. I also need to add that in bubble, the expression is written as text, do not use the dyanmic data button for operations (adding, substracting, multiplying, etc) as it may not work properlly, use dynamic data only to retrieve values/data from your database or previous steps. For example i had to calculate this formula T * atan(0.151977 * (HR% + 8.313659)^(1/2)) + atan(T + HR%) - atan(HR% - 1.676331) + 0.00391838 * (HR%)^(3/2) * atan(0.023101 * HR%) - 4.686035 where T and HR% are values that i have in my database, i wrote the expression just like that and then changed T and HR% for the dynamic data that links them to my database, i hope this helps someone else

I am incredibly amazed at the reviews saying it doesn't work. I have used this plugin for over 1 year now, it absolutely works. It's the simplest plugin ever! Yeah there's no documentation, but there's none because it is too simple you don't need one. If you don't know how expressions are written just try different stuff and you'll see which works. In any case, here are some: A. Parentheses are supported, even multiple and nested. B. * is multiply, + is add, - is subtract, / is divide, ^ is exponent. Real kudos to the author for this.
