As Zero searches to find his place, he learns of his additive and multiplicative identities, and then he establishes place value.

Equal parts action and humor add up to a wholly entertaining introduction to simplifying fractions, in this one-of-a-kind math picture book story. When a valuable fraction goes missing, George Cornelius Factor (a.k.a. GCF) vows to track it down. Knowing that the villainous Dr. Brok likes to disguise his ill-gotten fractions, G.C.F. invents a Reducer—half ray gun, half calculator— that strips away the disguise, reducing the fraction to its lowest common denominator and revealing its true form. With the Reducer in hand, George seeks out Dr. Brok in hopes of retrieving the missing fraction. David Clark’s illustrations are packed with humorous details as well as clearly defined fractions and their corresponding reduction equations.

Zero. Zip. Zilch. Nada. That's what all the other numbers think of Zero. He doesn't add anything in addition. He's of no use in division. And don't even ask what he does in multiplication. (Hint: Poof!) But Zero knows he's worth a lot, and when the other numbers get into trouble, he swoops in to prove that his talents are innumerable.

Looks at counting systems and the history of the number zero.

"A ... new philosophy and ... guide to getting the most out of your money--and out of life--for those who value memorable experiences as much as their earnings"--

A NEW YORK TIMES NOTABLE BOOK The Babylonians invented it, the Greeks banned it, the Hindus worshipped it, and the Christian Church used it to fend off heretics. Today it's a timebomb ticking in the heart of astrophysics. For zero, infinity's twin, is not like other numbers. It is both nothing and everything. Zero has pitted East against West and faith against reason, and its intransigence persists in the dark core of a black hole and the brilliant flash of the Big Bang. Today, zero lies at the heart of one of the biggest scientific controversies of all time: the quest for a theory of everything. Within the concept of zero lies a philosophical and scientific history of humanity. Charles Seife's elegant and witty account takes us from Aristotle to superstring theory by way of Egyptian geometry, Kabbalism, Einstein, the Chandrasekhar limit and Stephen Hawking. Covering centuries of thought, it is a concise tour of a world of ideas, bound up in the simple notion of nothing.

A number/color book reminding us that it just takes one to make everyone count.

Farmer Worth discovers that a special tree on his farm produces different kinds of money, depending on what animal fertilizer he uses.

The invention of numerals is perhaps the greatest abstraction the human mind has ever created. Virtually everything in our lives is digital, numerical, or quantified. The story of how and where we got these numerals, which we so depend on, has for thousands of years been shrouded in mystery. Finding Zero is an adventure filled saga of Amir Aczel's lifelong obsession: to find the original sources of our numerals. Aczel has doggedly crisscrossed the ancient world, scouring dusty, moldy texts, cross examining so-called scholars who offered wildly differing sets of facts, and ultimately penetrating deep into a Cambodian jungle to find a definitive proof. Here, he takes the reader along for the ride. The history begins with the early Babylonian cuneiform numbers, followed by the later Greek and Roman letter numerals. Then Aczel asks the key question: where do the numbers we use today, the so-called Hindu-Arabic numerals, come from? It is this search that leads him to explore uncharted territory, to go on a grand quest into India, Thailand, Laos, Vietnam, and ultimately into the wilds of Cambodia. There he is blown away to find the earliest zero—the keystone of our entire system of numbers—on a crumbling, vine-covered wall of a seventh-century temple adorned with eaten-away erotic sculptures. While on this odyssey, Aczel meets a host of fascinating characters: academics in search of truth, jungle trekkers looking for adventure, surprisingly honest politicians, shameless smugglers, and treacherous archaeological thieves—who finally reveal where our numbers come from.

OVER 300,000 COPIES IN PRINT, WITH A NEW CHAPTER ON THE 2018 TAX CUTS. There's a massive freight train bearing down on the average American investor, and it's coming in the form of higher taxes. The United States Government has made trillions of dollars in unfunded promises for programs like Social Security and Medicare—and the only way to deliver on these promises is to raise taxes. Some experts have even suggested that tax rates will need to double, just to keep our country solvent. Unfortunately, if you're like most Americans, you've saved the majority of your retirement assets in tax-deferred vehicles like 401(k)s and IRAs. If tax rates go up, how much of your hard-earned money will you really get to keep? In The Power of Zero, McKnight provides a concise, step-by-step roadmap on how to get to the 0% tax bracket by the time you retire, effectively eliminating tax rate risk from your retirement picture. Now, in this expanded edition, McKnight has updated the book with a new chapter on the 2017 Tax Cuts and Jobs Act, showing readers how to navigate the new tax law, and how they can extend the life of their retirement savings by taking advantage of it now. The day of reckoning is fast approaching. Are you ready to do what it takes to experience the power of zero?
