	Math is very straight forward in Python. + adds, - subtracts, / divides, and believe it or not * multiplies. The main thing to comment on is %. % divides a problem and then returns the remainder.

	When the step indice is negative it is important to remember to make sure that the first indice is calling an element that comes later in the string, tuple or list than the second element. Just as in the last example '''-2''' is representing '''8''' while '''1''' is representing 2.
