Ray's Intellectual Arithmetic

Ray's Intellectual Arithmetic. 141 pages. Intellectual Arithmetic begins by reviewing the basic concepts covered in Ray's Primary Arithmetic, adding more problems and raising the difficulty. The book then adds the new concept of Fractions. Finally, it follows fractions with the similar concept of percentages. As these concepts are introduced, applications for the problems are given, showing the child how to solve increasingly complex problems, such as how to divide the rent of a farm between two people considering that one mans livestock eats 1/3 less.
