# uses map enumerator for the array of matrix values - remember to use the three-dot notation as it omits the last value since array starts at 0
# matrix[i][i] indicates the array position of each diagonal value for each row (row, column will be the same value for a square matrix
# reduce(:+) is an enumerator method sums up the block values that were just mapped from the array
