Formulas are the heart and soul of Excel, whether you’re using Excel to build a business, run a budget, or solve your math homework. In Excel Formulas: Halfwit to Hero you get a no-fluff introduction to the essentials of formula writing by master explainer and best-selling author Matthew MacDonald.Learn by Doing: In the past, computer books were giant doorstops that could crush you if they fell from a high shelf. This isn’t that sort of book. Instead, you'll "learn by doing" with the exercises on the companion website (http:lab.halfwit2hero.com). Each chapter has at least one step-by-step tutorial that gets you to practice the new concepts you've learned before theycan drop out of your brain. Yes, this approach requires more work than breezing through the book on your sofa while watching The Bachelor in the background. But the payoff is immense. Instead of ending this book as a person who’s "kind of" familiar with Excel, you’ll be someone who’s developed real Excel skills. And when someone asks you about an Excel formula feature, your reaction won’t be "That sounds vaguely familiar"—it will be "I tried that out myself."
