This book is devoted on some recent investigations on multiplicative elementary mathematics. The book contains four chapters.
In Chapter 1, we define the set $\mathbb{R}_{\star}$ of multiplicative real numbers and we prove that it satisfies all axioms for a field. We introduce an order in $\mathbb{R}_{\star}$, the power of multiplicative real numbers, multiplicative absolute value. We deduct some of their properties.
In Chapter 2, we define...
