Hi :) By f_(x) I meant f(x)! I try to figure out how to automate the calculation of these numbers:
Row 1: f(x) Row 2: Numbers that when summed will yield f(x) (Row 1) Row 3: Numbers that when summed will yield Row 2 Row 4: etc.... Many thanks for your answer! I'll try to implement that triangle tomorrow!
