ncalc | Solve some problem algebra | Apps library

I have a dynamic formula that needs calculation.

Here's a sample (var1 * var2) / (var3 * (23 * 100))

These variables will be replaced with actual numbers because they are user input. Currently, I am using power automate flow that connects to my web API to throw any calculation and solve it. then send back the result. I am using NCalc and/or DataTable on the API.

What I was hoping to do was to pass the calculation in any Control like label or text. If you put 1+1 to the Text property of a Label Control. It will show the number 2 right away but since I am passing string it doesn't work. I can use something like this Value("100" * "300") and this works as long as we stick with math operators only but fails when we have the open and close parentheses like this (21 * 100) / (0.43 * (23 * 100))

I will appreciate it if you have a workaround in mind. Thank you in advance.

I need this to loop from -n to n but this only produces one co-ordinate so far. Does anyone know any easy quick fixes so I can have values from -n to n (step 1) subbed into the y equation id input?

I'm also not sure if I'm using the expression section correctly as I've never tried NCalc before today.

I have made the corrections suggested by Craig Estey. The code now compiles and work. This is the revised code:

I'm working on financial app, so I care about accuracy and I need to evaluate formula expression like:

I want to calculate a string in C# using either NCalc or DynamicExpresso library, the problem is, when the calculation gets complex and the numbers are big, it returns the wrong result. For example the code below returns -808182895 when it should return 3486784401

Everytime I attempt to copy Brevity.Api.xml, it'll always end up with a 'Not found' issue and would cause build failures. Listing the files in the directory of the where the docker build is at before executing the copying instructions show that the file is indeed there. What am I missing? Check step 11 (At the bottom of the log) in the build log

Example a: √12 =2√3

Example b: √16 = 4

I am trying to get both.

Whilst I can of course use Math.Sqrt(4) to achieve outcome b, I've no idea how to achieve a, or further how to get both to work simultaneously which is the goal. How do I achieve this type of simplification in C#?

I have tried several libraries including MathNet, Symbolics and NCalc with no success. This post may have solved it in c++, although I do not know for sure. My attempts at converting that solution to even see if it worked were very much a failure:
