It was part of the Johnson Series, which also included a 271-page, 35-cent Primary Book.
The book's ambitious contents include:
- Notation and Numeration of Integers
- Tests of Divisibility
- Aliquot Parts
- Measures of Value, Capacity, Weight, Extension, Volume and Time
- Longitude and Time
- The Metric System
- Profit and Loss
- Simple Interest, Annual Interest and Compound Interest
There is also a section on Practical Measurements, including discussions of using mathematics for painting, plastering, measuring lumber, brick work, stone work, carpeting and papering. Handy stuff!
Now, as we're getting back into the swing of the school year, try your hand at some of the word problems featured in the textbook.2 The answers are down below, under the footnotes.
A. A farmer bought two cows, giving $29.50 for one and $36.75 for the other. He gave in payment a wagon worth $42.25, and the rest in cash. How much money did he give?

1. Here's a neat inscription from 1902 on one of the book's first pages:
2. I realize that barraging readers with a series of math word problems is probably not the best way to encourage them to return to Papergreat. But I'm trying to mix it up. It can't be all about fluffy chickens and root-beer advertisements here. We need some variety!
B. 320 bushels
C. 26⅔ hours
D. 24 days
