Expression Evaluator

High-precision arithmetic (10 decimals). Use 'j' or 'i' for imaginary.
Use '∠' or '<' for polar notation (e.g., 20<-30).
For desktop, use "Win + .", go to Symbols, then Math Symbols, and search for '∠'.

System of Equations

Solve systems of linear equations.
One equation per line (e.g., 3x + 10<45 = 0).
Flexible variables: a, b, c, i1, i2, v1, v2, etc.
