This is first work if its kind. It brings representations of natural numbers from 0 to 5000 written in terms of single digit "a". It is in such a way that if we replace a by 1 to 9, it always remains the same. To bring these results only basic operations, such as, addition, subtraction, … Continue reading Single Letter Representations Of Natural Numbers

# Flexible Power Representations: Unequal String Lengths

This paper works with representations of natural numbers from 0 to 11111 written in terms of expressions with additions, subtractions and exponents. Digits used are from 1 to 9 in such a way that for each number, there are same digits in bases and exponents with different permutations. Some numbers can be written in more than one … Continue reading Flexible Power Representations: Unequal String Lengths

# Crazy Representations of Natural Numbers

Natural numbers from 0 to 11111 are written in terms of 1 to 9 in two different ways. The first one in increasing order of 1 to 9, and the second one in decreasing order. This is done by using the operations of addition, multiplication, subtraction, potentiation, and division. In both the situations there are … Continue reading Crazy Representations of Natural Numbers

# Running Expressions: Increasing and Decreasing Orders

Running expressions are understood as expressions written in terms of 1 to 9 and 9 to 1 or 9 to 0 separated by one or more equality signs. Each digit appears once with basic operations, along with factorial and square-root. The work is written in increasing and decreasing order of digits, i.e., from 1 to … Continue reading Running Expressions: Increasing and Decreasing Orders
