Answer
Pascal's triangle is a triangular array of binomial coefficients. Each number is the sum of the two numbers directly above it.
Here's the beginning of Pascal's triangle:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
The numbers in the triangle correspond to the coefficients in the expansion of binomials. For example, the row 1 4 6 4 1 gives the coefficients for (x + y)⁴: 1x⁴ + 4x³y + 6x²y² + 4xy³ + 1y⁴.
