The use of numbers is really important in our lives, it does not matter what intellectual or scientific field we are studying, we can use them to several purposes even to get fun, to know these uses will help us to understand ...

Let s be an integer greater than or equal to 2. A real number is simply normal to base s if in its base-s expansion every digit 0,1,…,s-1 occurs with the same frequency 1/s. Let S be the set of positive integers that are ...

We give an algorithm to compute an absolutely normal number so that the first n digits in its binary expansion are obtained in time polynomial in n; in fact, just above quadratic. The algorithm uses combinatorial tools to ...
