**About Gadzillion**

Gadzillion is a free and ad-free educational resource to basic the number skills required to have a sense of perspective. Suitable for children from ages 2 to 1.2x10^2.

All successful business people are good at this game. Few others are. Maybe we should teach this skill?!?

No exercise in school rewards students for being close, fast. But the real world does!

Gadzillion helps you estimate numbers close enough and fast enough to make them a useful part of your intellectual life. Educators that always insist on being exactly right no matter how long it takes discourage students from gathering the rapid-fire number skills that let you think on your feet. If you need to fetch a calculator whenever someone mentions a number, you will never succeed in business!

People shouldn't laugh when they say "I don't have a head for numbers". They should get a head for numbers! It doesn't take very long, using tools like Gadzillion.

People who use Gadzillion include:

- Students who want to gain a sense of proportion in various fields.
- Students who are studying scientific notation, exponents, and proportions.
- Students who are studying significant figures and quantitative analysis.
- Educators who are looking for fun and competitive ways to help students master one of the most important basic skills.
- Social Change Groups who want to help their members gain a sense of proportion about issues, empowering them to communicate effectively.

Gadzillion.org uses interactive quizzes on a multitude of subjects to help participants gain comfort and knowledge with very large and very small numbers.

On Gadzillion, people take quizzes created by their peers, or by Gadzillion staff.

People can become members, which simply allows their scores to be tallied, and gives them the opportunity to create and share new questions and quizzes for others.

Gadzillion.org is dedicated to increasing the knowledge of its members in the use and understanding of large numbers through a series of fun and competitive quizzes designed to allow better understanding of the real world social and economic challenges we face today.

By better understanding the numbers which lie behind these issues, we can have hope that people around the world will become increasingly knowledgeable and more involved in the political process leading to the changes necessary to ensure a sustainable world.

Please complete the form to register and you can immediately begin taking and creating exciting and mind simulating quizzes on any subject. Best of all, you will be competing with the entire group of participants and the top five competitors with the highest scores will be listed on the front page of the site.

Innumeracy is as bad as illiteracy. When you get over your number numbness you will feel like the one-eyed-man in the land of the blind. You will laugh at crazy situations everywhere created by people who literally can't put 2 and 2 together (if they are exponents.)

Have fun and good luck testing your knowledge!

**Special Message to Educators**

** **

The Gadzillion Education Program supports educators and students in their pursuit of a greater understanding and assimilation of concepts involving large numbers.

Though educating our children, we create a future generation of leaders and innovators who will understand the issues better and embrace the process through a confident and practical understanding of the sheer amount represented by large numbers extending almost to a septillion.

Educators have the ability to create and share quizzes with their students as well as having the scores for quizzed reported for all participants in the quiz. Students are encouraged to try the same quiz over several times until they get an excellent score, demonstrating their newfound sense of perspective over the subject.

Students can "Turn In" their scores to their teacher by copying the "Final Score" page and emailing it.

**About Us**

Gazillion was created by students and teachers as a project to help people better cope with the numbers that effect our lives.

** **

Innumeracy is defined by mathematician John Allen Paulos as "an inability to deal comfortably with fundamental notions of number and chance." At Gadzillion, we consider innumeracy to be a larger problem than illiteracy because a greater number of people are affected by innumeracy. Experts report that approximately 94.5% of all Americans are innumerate.

Gadzillion’s mission is to make people comfortable with and able to reason about large numbers. Our method is a fun and exciting set of games and quizzes which help people compete in an environment designed to allow better understanding of concepts involving large numbers.

Critical numeracy means that citizens are empowered with the necessary functional skills to participate fully in civic life, skeptically interpret advertising and government statistics, and take political and social action. Confidence in their own understanding of large numbers will allow people to use language, literacy, and numeracy together as vehicles for examining political and social issues in a manner that allows them to better analyze the issues and come to an educated decision based on their own views.

Good Justification for Gadzillion **

We always hear that the US Govt has budgeted Billions of dollars to various projects. As taxpayers and future taxpayers, we are picking up the tab. But how many taxpayers know how much must come out of the average person's pocket to make up a billion? $3.30. Knowing that transforms your understanding of politics. They say "We are spending $30 Billion for X." and you understand "I'm paying $100 for X".

Notes from an excellent book on Climate and Energy, By David JC MacKay, Without Hot Air, that demonstrates some nice relevant arithmetic of the sort we want to promote.

"I’d like to emphasize that the calculations we will do are deliberatelyimprecise. Simplification is a key to understanding. First, by rounding thenumbers, we can make them easier to remember. Second, rounded numbersallow quick calculations. For example, in this book, the populationof the United Kingdom is 60 million, and the population of the world is6 billion. I’m perfectly capable of looking up more accurate figures, butaccuracy would get in the way of fluent thought. For example, if we learnthat the world’s greenhouse gas emissions in 2000 were 34 billion tons ofCO2-equivalent per year, then we can instantly note, without a calculator,that the average emissions per person are 5 or 6 tons of CO2-equivalent perperson per year. This rough answer is not exact, but it’s accurate enough toinform interesting conversations. For instance, if you learn that a roundtripintercontinental flight emits nearly two tons of CO2 per passenger,then knowing the average emissions yardstick (5-and-a-bit tons per yearper person) helps you realize that just one such plane-trip per year corresponds to over a third of the average person’s carbon emissions."

**Tips on How to Win at Gazillion**

- Just get close enough! We give full credit for being pretty close.
- Take the same quiz three times!
- Learn scientific Notation, so you know that 300,000 = 3E5 = 3*10^5
- Learn to Multiply by Adding Exponents. Divide by Subtracting Exponents. Now you can multiply and divide huge numbers in your head.
- You can also multiply and divide "mechanically" as if you were using a slide rule, by moving the answer slider up and down to multiply and divide. For instance, if the question was "how many minutes in a year" you could calculate it by putting the slider on 24, and then moving it 3600 to the left, which is about 3.5 ticks, and then another 360 which is about 2.5 ticks to the left.
- Moving the slider half a tick doesn't multiply by 5 because it is and exponential scale. Half a tick is a factor of the square root of 10, about 3.16.
Note this game counts you as right if you are within a factor of 3 or so.

It gives you extra points for being fast.

So it is best to go thru it fast and be close.

No extra points for being exactly right.

- Still too hard? Cheat! Turn on the audio hints.

**Tips for Advanced Creative Users**

- Make answers whole-numbers, not percentages, not proportions.
- Q: What percentage of Americans are Female"

should be rephrased

Q: "How many Americans are Female? A: 150,000,000 " - Make answer units as familiar as possible. If the conventional unit is unusual, you can include a conversion in the question.
- "Q: How many Bushels of Wheat fit aboard this cargo ship? (A bushel is around 35 liters) A: 35E8 liters"
- Rephrase question to make small number answers in to big number answers.
- "Q: How big is a bacteria? A: 3 micrometers"

could be rephrased

"Q: How many bacteria lined-up would equal one meter? A: 3.3E05"
