solveMacaulayExpansion -- compute the sum of a Macaulay expansion

Synopsis

Usage:

solveMacaulayExpansion l
Inputs:
- l, a list of pairs of natural numbers representing a Macaulay expansion
Outputs:
- an integer, representing the sum of binomials in the listl

Description

Given a list of pairs {{a_1,b_1}, ... ,{a_k,b_k}} this method yields the sum of binomials binomial(a_1,b_1) + ... + binomial(a_k,b_k).

Example:

i1 : solveMacaulayExpansion({{4,2},{3,1}})

o1 = 9
