Five Calculators, One Notebook

The book opens with five calculators: solar estimate, feed mix, home electricity, BMI check, and calorie needs. Each one shows its working in the same four blocks — the inputs, the formula, the result, and the source.

Every sample row still carries demo values: each page names the reference table it waits for, and nothing ships as fact until that table lands. Watch this space — the tables are the news we are actually waiting for.
