We were doing Calculus just to test how cool my Primary 5 son can be in the face of some supposedly "scary" problems.
And we were looking for a kid-friendly introductory book
We did check out books at our Popular stores. In Singapore, Calculus is taught in A Maths in Secondary 4. The textbooks, the workbooks, the supplementary books there did not foresee customers like us.
We did find Business Calculus Demystified, a wonderful book, a great one. But it didn't meet our requirement of " just 1 or 2 hours."
We kept looking till we found "Calculus Made Easy."
Strangely, a book published in 1910 is the most suitable for the 21st century:
It also captures the spirit of the calculus reform movement:
The photos were taken form "Calculus Made Easy" the 1998 Edition's introduction by Martin Gardner.
By this time, we, both father and son, were very cool.
- We know more relevant branches of Maths, other than Calculus.
- Tough big books are not our problems, but the problem for the authors and the publishers.
- We can bypass them with cooler nicer books.
- a few chapters of Calculus Made Easy
- a few sections of a workbook from Popular store
- a few chapters of Business Calculus Demystified
I believe that this experience will help him with other areas of studies too.
