ZENNY RIEL: An Arithmetic Notebook In View

By: C. Zenaida Riel

 

About the Book

The ZENNY RIEL model of mathematics is a no-trial-and-error, fast and sure approach to the arithmetical processes.

Now with an illustration of the modified abacus, ZENNY RIEL will give you confidence in mathematics and adjusts the narrative, for once making the tool (calculator or abacus) obsolete for learners—and not the other way around!
