Benjamin and Michael Shermer. However, you can use these decks even if you do not have this book as it doesn't really depend on that. The best thing is that you can start as a beginner from the addition and subtraction and gradually go up to the 2 digit squares, 2/3 digits multiply and divide, percentage, Compound Interest then mnemonics and the final one. These mnemonics are based on the book which you can also find on http://numzi.com/numzi/ Problems were generated using python scripts manually The card contains the following subdecks:

Soo good

I have only begun using this deck. This deck does not teach mental math. But, it is good for memorizing specific mathematical problems. If you want to learn the Mental Math that this deck's author promotes then, before using this deck as "_practice_" for Mental Math, watch the author of The Secrets of Mental Math by Arthur T. Benjamin, Ph.D. video on Youtube (https://youtu.be/qaNO6y0F6CA).



There is a sub deck of "Mnemonic" with the decks of "Number to Text" and "Text to Number" with one of the cards being:

Front: 645

Back:

sharla

SH aa R L ah

...

churl

CH ah R L



Say what?

Please use the "Description" tab on the deck to provide enough information that these such cards don't look like like something ridiculous.

If "sharla, SH aa R L ah" is something that comes out of only your own mind it's not going to do many people any good.

If it's a mnemonic techniques then please cite the source and an HTML link to the source would be even better.



Perhaps provide a deck that has cards the explains the mnemonics as well as cards for remembering the mnemonics.
