Publisher's Summary

 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.

Excellent but need PDF

This is an excellent Audio Program by my beloved Dr. Art.

Only thing missing is the PDF book. please vote for my idea up so Professor Arthur releases the PDF. Math need reading and doing some practice. the PDF can include practice questions and quizzes to improve learning and a summary for the mental tricks taught in the audio book.

Please vote for my idea up. i was waiting for this book for a long time.

appreciate u guys..

Fun to listen to!

I love numbers and love playing with them. This audiobook teaches how to do mental math with almost no work. I listened to it in my car and was able to understand and learn what Art Benjamin explained. I recommend it for people who think that numbers are difficult to deal with and also for others who like me, want to have fun doing calculations without the use of a calculator. There are fun little tricks to do difficult calculations like 3 digit by 3 digit additions, multiplications and divisions. The last chapter is a lot of fun; Art teaches how to do simple "tricks" using numbers. I wish he would show more of those!

Very easy to listen to and a lot of fun.

Wow- Game Changer

This audiobook is perfect. In the past, I actually tried to watch a video or read a book by this author, but he’s right - an audiobook is the best format so you can hear the numbers. I thought I was good at mental math, and he raised my confidence and abilities tremendously. Thanks Art Benjamin and Audible!

Easier math.

At the moment I am only through the first chapter, but I have already picked up immensely helpful tips. I am one of those people who is very slow with math, and It feels miraculous to be able to calculate bigger numbers in my head with just a couple of tricks!

You'll win a LOT of bar bets.. free beer! :)

This has been one of the most amazing audio books I've listened to! Art is energetic and funny, and he constantly reminds you that the audio book is short because you can PAUSE and do the math before he tells you the answer and works through the problem. I have studied vedic math and managed to get lost; this unforgettable tome has enlightened me and won me an awful lot of bets based on "stupid human tricks" with math. Note, I'm sure the author doesn't approve of using his work to earn free beer, but it's one heck of a side benefit. :)

Really great narration

This is narrated very well. Honestly, I am terrible at math. Terrible. This book was a little too advanced for me, and I will return to it later on. But it's a solid book, well put together and well-narrated. I recommend it for someone wanting to hear some great ideas about mental math while driving to work or walking around. It will give you a lot to think about.

For a niche audience

This is an interesting book, full of useful tips and mathematical shortcuts. But it is definitely unlike other non-fiction books.

I'm used to listening to books at double, even triple speed, gleaning some interesting nuggets of information along the way. You can't do that with this book. I listened at single speed and had to pause frequently and rewind occasionally.

This is less of a book and more of a course. Perhaps it would be better as a website or app that can teach and drill the user.

Although it is interesting to imagine being able to, say, multiply several two-digit numbers quickly in your head, you won't actually be able to do that unless you practice, practice, practice. And then if you don't use these skills in a while, they'd be easy to forget. So don't even bother starting this audiobook unless you're ready to commit to hours of practice.

I imagine there are two audiences for this book: those who love doing math for fun, and educators who want to make their students work through exercises like these in order to be more efficient at basic math. If you simply like enjoying learning new things in general, this likely isn't for you.

I go through about a hundred audiobooks a year. It's rare for my to abandon a book. I got about halfway through this before realizing it was taking more time and effort than I realized and - since I didn't intend to keep practicing for the rest of my life - it wouldn't provide much value.

This could be a great book, but only for specific audiences.

A great course from a truly exceptional teacher

Highly recommend. The enthusiasm that Art has for Math is infectious and this book is gold dust. The tips on the 9 times table were easy enough for my 6 year old grandson to learn. Plenty of tips and challenges. Great for everyone. Take a bow Arthur T. Benjamin.

Great book!

If you have assumed your brain just isn't wired for maths and that frustrates you, then I thoroughly recommend this book.
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.

Arithmetic not Math

A must for those who lack confidence in arithmetic, or who are moving up in education.
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.

Inspirational book.

This has helped me to look at mathematics with another outlook to for me a daunting subject. There are some useful hints and tips in this audible book which has given me a little more confidence. I will be revisiting this book to familrise myself once again and become a more successful mathematics student.

Lost my fear of mental maths

I have struggled with maths my whole life long and this book was amazing. Using tricks from this book, I was able to show off in front of a maths wiz and perform mental maths way faster. Not gonna lie, the look on his face was worth it. The only problem is, as I am unlikely to keep applying these skills every day, I will likely soon forget everything I have learned. So while this book will absolutely blow your mind in terms of how easy it is to do mental maths using these tricks, you will unfortunately need to practise them often in order to remember them - it's just how our primate brains work.

culturally insensitive

This course is biased towards European left-to-right language systems. It expresses left-to-right thinking as "right", and implies all other kinds of thinking as wrong. Also the tone is extremely patronising.
