@ -5,11 +5,14 @@ Currently the following functions are implemented:
* `math avg`: Finds the average of a list of numbers or tables
* [`math eval`](math-eval.md): Evaluates a list of math expressions into numbers
* `math min`: Finds the minimum within a list of numbers or tables
* `math max`: Finds the maximum within a list of numbers or tables
* `math median`: Finds the median of a list of numbers or tables
* `math min`: Finds the minimum within a list of numbers or tables
* `math mode`: Finds the most frequent element(s) within a list of numbers or tables
* `math stddev`: Finds the standard deviation of a list of numbers or tables
* `math sum`: Finds the sum of a list of numbers or tables
* `math product`: Finds the product of a list of numbers or tables
* `math variance`: Finds the variance of a list of numbers or tables
However, the mathematical functions like `min` and `max` are more permissive and also work on `Dates`.
