Spring, TX Author Publishes Book on Mathematics

By: PR Leap
( ZENNY RIEL: An Arithmetic Notebook In View, a new book by C. Zenaida Riel, has been released by Dorrance Publishing Co., Inc.

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!
