Exercise 4. This software allows you to input positive integers n_1, n_2>, n_3, ... , n_k, where k <= 5, and compute the number of elements in Zn_1+Zn_2+...+Zn_k of any specified order m. Use this software to verify the values obtained in Examples 3 and 4. Run the software for n_1=6, n_2=10, n_3=12, and m=6.
