What is the pascals triangle used for?

Answer 1

AnswerPascal's triangle is a triangular array of the binomial coefficients in a triangle. It is named after the French mathematician Blaise Pascal. It is mainly used in probability and algebra.

1 Row 0

1 1 Row 1

1 2 1 Row 2

1 3 3 1 Row 3

1 4 6 4 1 Row 4 etc.

Each number in the triangle is the sum of the two directly above it. The value of a row, if each entry is considered a decimal place, is a power of 11. So, in row 2, '1,2,1' becomes 112, and '1,5,10,10,5,1' (which will be in row 5) becomes, after carrying , 161,051 which is 115.
