This is my classic Polynomials And Scientific Calculator. It can perform a wide range of operations, including polynomial arithmetic (+, -, *, /), root finding, as well as logarithmic, trigonometric, and exponential functions. You can also define custom functions and work within the realm of real or complex numbers. The calculator includes built-in constants like 'π' and 'e', and supports binary, octal, and hexadecimal inputs by using the prefixes &b, &o, and &h, respectively.

Additional features include calculus operations such as derivatives, integrals, and Lagrange interpolation, as well as matrix operations And the solving of systems of equations and differential equations. For guidance, you can refer to examples or view intermediate steps when available.
