In mathematical manipulations one often has to multiply the same number by itself repeatedly, so that one has such expressions as
This sort of thing can rapidly become both tedious and difficult to read, and it is convenient to have a shorthand notation that conveys the same information not only more concisely but also (once one is used to it) more clearly. Exponents fulfil this need. The simplest use of an exponent i is to raise a number to its ith power, i.e. to show that the number is to be multiplied by itself i times, the exponent being written a little above the number that it operates on.
