Division by zero in real and complex number arithmetic and some of its implications

July-December, 2022 - Vol 15 Num. 2

In this paper, an attempt is made to include division by zero in ordinary arithmetic. Counting or measuring is done to get the value of multiples, powers, quotients, sums and differences of zeros. Zero divided by zero is taken to be equal to one. There are many infinities and many zeroes. The biggest of all infinities...
