Mental Math: From Ancient Coins to Crypto

By Harry Lima

Mental Math: From Ancient Coins to Crypto will train your brain to see patterns, solve problems, and handle numbers with ease, without paper, pencil, or a calculator.

Numbers are everywhere in daily life: from checking the time and splitting a restaurant bill, to figuring out discounts, loans, or the value of digital money. Yet, most people hand this responsibility over to calculators or apps, believing that math is too abstract or too hard. This book proves otherwise. Mental Math is faster, clearer, and more powerful than you think.

You'll learn how to see shortcuts, break big problems into smaller steps, and find solutions instantly. Through stories, real-world examples, and simple strategies, this book takes you on a journey across the history and future of numbers.

Each chapter brings math back into real life: markets, negotiations, investments, science, and daily routines. This book trains your brain to be sharp and adaptable. The journey from ancient coins to modern crypto shows one truth: math has always been the language of trust, trade, and progress. And with this book, you'll finally master it, in your mind.
