The first row (1 & 1) contains two 1's, both formed by adding the two numbers above them to the left and the right, in this case 1 and 0 (all numbers outside the Triangle are 0's). So we start with 1, 1 on row … For example-. We can use this fact to quickly expand (x + y) n by comparing to the n th row of the triangle e.g. 2. You can compute them using the fact that: nCk = n! The top row is numbered as n=0, and in each row are numbered from the left beginning with k = 0. More details about Pascal's triangle pattern can be found here.
