## What is Incredible Numbers!?

Selected by Apple as Best of 2014, and winner of the 2015 Digital Book Award for Best Nonfiction App.

Bestselling author Professor Ian Stewart is your guide through Incredible Numbers. Numbers define the patterns of sunflowers; they bring pleasure through music; and they help us answer existential questions like; ‘How many ways are there to lace my shoes?’ Interactive examples – from simple equations to a working Enigma machine – put the beautiful concepts behind mathematics at your fingertips.

“A measure of Ian Stewart’s success is that he’s able to give a clear path through some very hairy mathematics.” – Times Higher Education Supplement

There’s so much more than a few screenshots can show:

– 23 articles crafted by Prof. Ian Stewart, embedded with 71 groundbreaking interactive demonstrations.
– 23 bespoke interactive sections that let you immerse yourself in the beautiful patterns and concepts behind each topic.
– 15 of Ian Stewart’s famous mathematical puzzles.

Topics include:

• Infinity – Explore infinity and understand what it really means to say something is infinite. 
• Pi – Unwrap the mysteries of pi to see why this strange number is so important and why it’s not just about circles.
• Music – Music and math share the beauty of finding patterns in complexity. Detailed interactives show you how they relate in real, meaningful and fun ways.
• Codes – See how the power of numbers can unlock complexity in codes.
• Nature – See how numbers work in nature by looking at the Fibonacci sequence and how it appears in the real world in beautiful and surprising ways.
• Primes – Discover the mysterious patterns in prime numbers, and why they are so important.
• Polygons – Get to grips with shapes and polygons. Classical geometry is just another way to think about numbers!
• Factorials – How many ways can you lace your shoes? Did you know that if you have 4 eyelets, there are 24 possible lacing styles? With 12 eyelets there are 479,001,600 possibilities. See why this is so in Factorials! 

Incredible Numbers aspires to convince you that maths is beautiful. Mathematicians know this already. The great solutions and proofs shine to them, but their underlying beauty has been hidden behind abstract algebra and complex equations. Until now. 

If you enjoy this app, don’t forget to rate it in the App Store.

### 5/5 — Very good

*2021-02-01*

I like how it is more quality over quantity, very good!

### 5/5 — High quality content-- a rare gem of an app

*2018-07-26, version 1.2.0*

This is really good quality content. Most "maths" apps are just formulas or calculators or random computational exercises. This one actually gives a lot of motivation and intuition behind important mathematical ideas. A great companion to the book of the same title.

If you're looking for a maths textbook with exercises and tutorials on solving equations, this isn't the app for you. If want to read about and explore mathematical ideas like infinity and primes, this is the app for you. It's got a handful of puzzles and mathematician biographies as well. The interactive aspects of it are informative and aesthetically pleasing, especially the geometric constructions.

I wish there were more apps like this. This is my favourite app from Touchpress.

**Developer response:** Many thanks for the kind words and the positive review! We're delighted to hear you're finding the app so useful! StoryToys Support Team

### 5/5 — Pretty Amazing.

*2014-10-20*

My 10 Year Old Son is really into Math at School. Go Figure. Myself? At Age 52, this program has taught me that what I do Not know about Numbers is vast...but this software is actually entertaining, he can't put it down and even I am amazed by it. When my Son let's me check it out of course...

### 5/5 — Wonderful

*2014-07-08, version 1.0.1*

A fantastic exploration of the wonder and beauty of mathematics

### 3/5 — Hmmm

*2014-05-13*

As usual good looking app from touch press. But very low on content.

### 3/5 — Nice try but not enough material

*2014-05-10*

This is a very greedy application. The price is too high and the amount of material is too low. But it is stylish. Also audio explanations would be much better then plain text.

### 1/5 — I don't get it!

*2014-04-07, version 1.0.0*

I love the beauty of Maths and numbers. I own several books on mathematical relationships, numbers, etc. so I thought I would love this App. Unfortunately the opposite is true.  I find there is a distinct lack of detail and creativity in the text.  It only moderately held my attention and only because I'm a diehard number lover.  My opinion is that it would bore anyone else to tears.  The puzzles were basic and the graphics were outdated.  I think with this App the only people you're preaching to are those already in the choir.

### 5/5 — Whiners

*2014-04-04*

Stop whining. My seven year old loves this app. If you like math you'll like this. Don't expect it to turn you into a math whiz if you already dislike math.

### 5/5 — Fantastic learning experience!

*2014-04-04, version 1.0.0*

This app uses the iPad medium to naturally explain some trickily math concepts like Fourier decomposition. I thoroughly recommend this app to parents and anyone who wants to explore maths but has always been afraid of the complexity.

### 1/5 — I Should Have Listened

*2014-04-03*

I should have listened to the other reviews and not bought this. I thought I could use it to teach my 16 year old some math because I am by no means a mathematician. I hated math growing up and this app just made me hate it even more.
