There are numbers of every kind: rational, actual, advanced, p-adic. The p-adic numbers are much less renowned than the others, yet they play a basic position in quantity conception and in different components of arithmetic. This undemanding advent bargains a extensive knowing of p-adic numbers.

From the experiences: "It might be the main appropriate textual content for newbies, and that i shall certainly suggest it to an individual who asks me what a p-adic quantity is." --THE MATHEMATICAL GAZETTE

Write and test a recursive function for the Fibonacci sequence 1, 1, 2, 3, 5, 8, ... ) Thus fibonacci@6D should return the 6th term in the sequence, and so on. 3. Write a recursive function called myDet, which must not call Mathematica’s Det function, for calculating matrix determinants by cofactor expansion. nb 37 È Session 3 In this session, there are three things you can opt to do.

7 Advanced Topic: iteration and recursion Suppose we wanted to rewrite Mathematica’s Factorial function from scratch— for non-negative integers, at any rate. nb 36 or n myFactorial1@n_D := Ì i i=1 This is an example of iterative code: the value of i is made to increase sequentially, and the product is built up as it does so . But there is another possible approach. Consider the following code: myFactorial2@0D = 1; myFactorial2@n_D := n * myFactorial2@n - 1D This may look like a circular definition.
