### KEY FEATURES
---

#### >> CORE CALCULATIONS (Powered by Math.js)

-   Full Arithmetic Suite: Standard operators (+, -, *, /, ^, %), parentheses.
-   Numbers & Precision: Integers, decimals, scientific notation. Supports precise fractions with `fraction()`.
-   Complex Numbers: Seamlessly work with complex numbers (e.g., `(2+3i)^2`).
-   Matrices & Vectors: Create, manipulate, and perform operations like `det(A)`, `inv(M)`, `A*B`.
-   Extensive Unit Support: Calculate with diverse units (length, mass, time, energy, etc.) and convert effortlessly (e.g., `5 ft + 10 cm in meters`, `100 km/h to m/s`).
-   Rich Function Library: Trigonometric (`sin`, `cos`), logarithmic (`log`), exponential (`exp`), statistical (`mean`), probability (`factorial`), and many more.
-   Constants: Includes `pi`, `e`, `i`, and others.
-   Variable Assignment: Store results or values in variables (e.g., `x=5`, `rate=9.8`).
-   User-Defined Functions: Create reusable functions (e.g., `area(r) = pi*r^2`).

#### >> SYMBOLIC MATHEMATICS (Powered by Nerdamer.js)

-   **Solve Equations:**
    -   Single equations: `solve(x^2-4=0, x)`

    -   Rearrange: `solveFor(E=m*c^2, m)`
-   **Calculus:**
    -   Differentiation: `diff(sin(x^2), x)`
    -   Integration (Indefinite & Definite): `integrate(exp(x), x)`, `defint(x^2, x, 0, 1)`
    -   Limits: `limit(sin(x)/x, x, 0)`
    -   Summation & Products: `sum(k, k, 1, n)`
-   **Algebra:**
    -   Factoring: `factor(x^2-1)`
    -   Expansion: `expand((a+b)^3)`
    -   Partial Fractions: `partfrac(1/(x^2-1), x)`
    -   GCD, LCM, Roots, Coefficients, Degree, Simplify, Complete the Square.
-   **Transforms:**
    -   Laplace & Inverse Laplace: `laplace(exp(a*t), t, s)`
-   **Other Tools:** `isPrime()`, `numerator()`, `denominator()`.
