Math for Dummies — Everyday Numbers, Without Fear and Without Scolding

The check lands on the table and everyone turns to look at you. Someone says "you split it." And something tightens inside you that has nothing to do with numbers.

It isn't that you can't. It's that one day, standing at a blackboard, someone made you believe you couldn't.

This book breaks that contract. No filler theory, no formulas to memorize: tamales, splitting the bill at a small Mexican diner, a kilo of meat at the butcher, the electricity bill, and a quesadilla stand that needs to know whether it's actually making a profit. You'll give change the way market vendors do, work out a 15% tip in ten seconds without a calculator, find out when the supermarket "value size" is actually costing you more, and read a chart while spotting the moment it's built to fool you.

Every chapter ends with exercises, and every exercise comes with its answer explained step by step — not just the number, the whole path.
