THANK YOU!
The tutorial consists of more than 200 live examples from 50 sections. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Below is the code for JAVA, the code for C# is almost identical.
Case 1: The square root √
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√2");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √2 = 1.4142135623730951
Case 2: The square root of the square root √√
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√√16");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √√16 = 2.0
Case 3: The square root and parenthesis √()
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√√(8+8)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √√(8+8) = 2.0
Case 4: The roots of various orders ∜ ∛ √
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("∜16 + ∛27 + √16");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: ∜16 + ∛27 + √16 = 9.0
Case 5: SIGMA summation operator ∑
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("∑(i, 1, 5, i^2)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: ∑(i, 1, 5, i^2) = 55.0
Case 6: Unicode name of a user defined argument
import org.mariuszgromada.math.mxparser.*;
...
Argument a = new Argument("α = 2π");
Argument b = new Argument("β = π/2");
Expression e = new Expression("sin(α) + cos(β)", a, b);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: sin(α) + cos(β) = 0.0
Case 7: Show all Unicode built-in keywords
import org.mariuszgromada.math.mxparser.*;
...
mXparser.consolePrintHelp("unicode");
