```

## 📖 Quick Start

### Arithmetic & Number Theory
```python
from mathcore import *

# Prime operations
is_prime(17)                    # True
prime_factors(120)              # [2, 2, 2, 3, 5]
fibonacci(10)                   # 55

# Combinatorics
binomial_coefficient(10, 3)     # 120
```

### Algebra with Step Display
```python
from mathcore import *

# Solve quadratic equation with steps shown
solver = EquationSolver()
roots = solver.solve_quadratic(1, -5, 6)
solver.display_steps()

# Output shows all steps:
# Step 1: Quadratic equation form...
# Step 2: Calculate discriminant...
# etc.
```

### Geometry & Line Collisions
```python
from mathcore import *

# Find where two lines collide
line1 = Line(Point(0, 0), Point(1, 1))     # y = x
line2 = Line(Point(0, 1), Point(1, 0))     # y = -x + 1
collision = find_line_intersection(line1, line2)
print(f"Lines collide at: {collision}")     # Point(0.5, 0.5)
```

### Calculus
```python
from mathcore import *

# Numerical derivative
f = lambda x: x**2 + 2*x + 1
deriv_at_2 = derivative(f, 2)              # ≈ 6.0

# Definite integral
integral_result = integral(lambda x: x**2, 0, 1, method='simpson')  # ≈ 0.333

# Find roots
root = find_root_newton(lambda x: x**2 - 2, 1.5)  # ≈ 1.414
```

### Linear Algebra
```python
from mathcore import *

# Matrix operations
A = Matrix([[1, 2], [3, 4]])
B = Matrix.identity(2)
C = A * B                       # Matrix multiplication

# Solve system
A_sys = Matrix([[1, 2], [3, 4]])
b = Matrix([[5], [11]])
x = A_sys.solve_linear_system(b)
```

### Statistics
```python
from mathcore import *

data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# Descriptive statistics
mean = DescriptiveStatistics.mean(data)
std_dev = DescriptiveStatistics.std_dev(data)
q1, q2, q3 = DescriptiveStatistics.quartiles(data)

# Linear regression
reg = LinearRegression()
x_data = [1, 2, 3, 4, 5]
y_data = [2, 4, 6, 8, 10]
reg.fit(x_data, y_data)
prediction = reg.predict(6)
r_squared = reg.r_squared()
```

### Probability
```python
from mathcore import *

# Normal distribution
normal = NormalDistribution(mean=0, std_dev=1)
prob_dens = normal.pdf(0)       # PDF at 0
prob_cum = normal.cdf(1.96)     # CDF value
quantile = normal.quantile(0.95) # 95th percentile

# Binomial distribution
binomial = BinomialDistribution(n=10, p=0.5)
prob = binomial.pmf(5)          # P(X = 5)
expected = binomial.mean()      # E[X]
```

### Optimization
```python
from mathcore import *

# Minimize function using gradient descent
f = lambda x: (x - 2)**2
x_opt, f_min = GradientDescent.optimize(f, x0=0)

# Or use genetic algorithm for global optimization
def objective(x):
    return sum(xi**2 for xi in x)

bounds = [(-5, 5), (-5, 5)]
solution, fitness = GeneticAlgorithm.optimize(objective, bounds)
```

### Differential Equations
```python
from mathcore import *

# Solve dy/dt = -y with y(0) = 1
def f(t, y):
    return -y

t_vals, y_vals = ODESolver.rk4_method(f, y0=1, a=0, b=2, n=100)

# Plot or analyze results
for t, y in zip(t_vals[:5], y_vals[:5]):
    print(f"t={t:.2f}, y={y:.4f}")
```

### Complex Numbers
```python
from mathcore import *

# Complex arithmetic
z1 = Complex(3, 4)              # 3 + 4i
z2 = Complex(1, -2)             # 1 - 2i
z3 = z1 + z2                    # (4 + 2i)
z4 = z1 * z2                    # (11 - 2i)

# Polar form
r, theta = z1.polar_form()      # magnitude, angle
z_polar = Complex.from_polar(5, 0.927)

# Mandelbrot set
iterations = ComplexAnalysis.mandelbrot_iteration(Complex(-0.7, 0.27), max_iter=100)
```
