You can make any of such favourable or detrimental numbers. The indicating of the good quantities is simple, but for adverse numbers, identical to indexes in Python, you rely backwards in the close for the start

The operator priority establishes which operators should be evaluated 1st. To stay away from ambiguity in values, precedence operators are required. The same as in normal multiplication approach, multiplication has an increased priority than this addition.
Sequence slicing is exact same, besides it first normalizes destructive indexes, and it may never go exterior the sequence:
