About this listen
No calculator? No problem! Whether a listener is prepping for a standardized test or just trying to figure out the check, mathematician Dr. Arthur Benjamin will teach listeners the fundamentals of mental addition, subtraction, multiplication, and division. From there, listeners will turn to the art of "guess-timation" for problems that don’t require an exact answer. Listeners will learn:
- Tricks and techniques to arrive at answers for large problems listeners can’t do in their heads.
- How to effectively memorize important digits, such as phone numbers, credit card pins, or the dreaded numerical call-in conference passcode.
- Little-known math techniques, including over-subtraction and the cashier’s method.
- Mastery multiplication tables through 20 and multiply a pair of 2-digit numbers.
- How to think of numbers from left to right and hear the numbers without the need to visualize anything.
- Tricks for adding and subtracting numbers as high as 4-digits and multiplying 2-digit numbers—without a calculator.
- How to rely heavily on mental estimation and tricks for converting fractions and decimals.
With Professor Benjamin’s engaging, fun-filled lessons, listeners soon find themselves amazing other people and, perhaps more important, themselves. Examples included in the lessons use real-world applications that apply to shopping, banking, tipping, cooking, gaming, gambling, and sports statistics. The skills learned in No Calculator? No Problem!: Mastering Mental Math will teach listeners the tools necessary to excel in school, personal finance, work, and life. Learn to allocate spending, manage time, and master life like a math whiz.
©2019 Audible Originals, LLC (P)2019 Audible Originals, LLC.This audio book fairly quickly covers the basics of mental arithmetic functions giving simple explanations and several worked examples of how and where to use the tools presented. As you would expect the audio book format works well for mental arithmetic.
Depending on your level of understanding the enthusiastic Sesame Street type presentation will either engage or drive you away. While not I suspect the primary target audience I was able to persevere with the book and it did provide several useful tools and a perspective that either I was never taught or have faded from memory in the intervening years....
Recommended if you need to brush up on your arithmetic or simply lack confidence in manipulating numbers.

It is well written and narrated by a patient teacher who understands that not everyone gets it first time. It doesn't work miracles, you still need to practice as the author says, but you'll be surprised by your newly acquired mathematical abilities.
Great book!
