I would like to perform the calculation with square root and ln in Math block which I see in [docs.thunkable.com](http://docs.thunkable.com). But I cannot find them on the [https://x.thunkable.com](https://x.thunkable.com).

 ![docs-thunkable](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/e/ae8f1ebf9ddbe725bfad510032c971d6f76aae3f.jpeg) ![x_thunkable](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/d/9daedfbf843bd107c72f51d67931e253d0a35db6.jpeg)

The last block on the Math panel

![%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/4/9/490d1cac16a2162eaa3615616b28f22914ee2987.png)

</div>

My understanding is this block for the constant value.  
But I would like to calculate with the other value. Example; the square root of 9. How should I do?  
And If I want to use the function log or ln, how can I do?

</div>

Then such a block

![%D0%B8%D0%B7%D0%BE%D0%B1%D1%80%D0%B0%D0%B6%D0%B5%D0%BD%D0%B8%D0%B5](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/1/114de2bb150c1640b0ad5b521d8d1cbde8920a7a.png)
