Math problems

A schoolteacher's manuscript exercise book containing a variety of simple and complex
mathematical problems, 1806, Pennsylvania.

 

including such all-time favorite as the two travelers
starting off from two points of origin traveling as such a speed  . . .
under the category: "Promiscuous Questions"
[promiscuous meaning "random" in this era.]

Some ciphers lead to architecturally beautiful answers

 

A second manuscript volume accompanying the exercise book
is an account book recording the tuition payment for students.

 

And . . . on the inside front cover of the exercise book is a bird doodle.
