State Pascal's triangle precisely and explain why it matters in 2-3 sentences.

# Pascal's Triangle Pascal's triangle is a triangular array of numbers where: - The apex and edges are all 1's - Each interior number equals the sum of the two numbers directly above it - Row n contains the binomial coefficients C(n,k) for k = 0 to n ``` 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 ``` ## Why It Matters Pascal's triangle is fundamental because it encodes the binomial coefficients used in the binomial theorem (a+b)ⁿ, appears throughout combinatorics (representing ways to choose k items from n items), and reveals deep mathematical patterns connecting algebra, probability, and number theory. Its applications range from calculating probabilities to understanding polynomial expansion to analyzing recursive sequences.
