Find the number of non-negative integral solutions: |x+y|+|w+z|=10. How does one approach this problem?
That makes sense! Do you have any tips on how to apply the stars and bars method?
Yes! The stars and bars method involves representing the partitions as stars and the dividers as bars. For example, if you had 3 stars and 2 dividers, then you can illustrate the partitions as **|*|. Counting the number of possible partitions involve selecting the positions for the dividers, which can be done using combination formulas.
