Excerpt from Durell's Arithmetic, Vol. 2
A number is a unit or a collection of units of the same kind. Thus, one apple is a number; also 5 apples is a number.
A unit of higher order is a unit formed by combining several smaller like units.
Thus, ten cents are ten like units which are combined to make a higher unit, the dime.

Paperback. Condición: New. Print on Demand. This book details the transition from Roman to Arabic methods of numeral expression and notation that occurred during the Middle Ages, along with the development of the decimal system, and general mathematical operations like addition, subtraction, multiplication, and division. The author explores how abstract number expanded mathematical applications, such as the fact that like numbers (such as apples and oranges) can be added, and unlike numbers can be added by converting them both into a more general term (such as fruit). These concepts, along with the invention of the zero symbol by ancient Hindu mathematicians and the Arabic notation system, laid the foundation for the arithmetic operations (and their innovations like reversed multiplication) used to this day.
