先猜一猜，再改变数字，看看钱去了哪里。这里没有唯一正确的公司。Predict first, change a number, then follow the money. There is no single perfect business.

先开一家小公司

  1. 选择一种熟悉的生意，给公司起名字并写一句介绍。
  2. 从收入到成本依次改变关键数字；每次只改一个，更容易看清原因。
  3. 右侧会立即更新公式、收入、成本、利润和现金。盈利柱在零轴上方，亏损柱在零轴下方。
  4. 保存方案 A，再调整出方案 B，比较两种经营办法。
  5. 生成个人报告，展示你的选择、结果和仍需验证的问题。

再做一个小实验

先选择生意和问题，再作出判断。答案出现后比较低、中、高三档，用图上的数字解释变化，并写下你的发现。

Build a small company

  1. Choose a familiar business, name it, and write one sentence about it.
  2. Change the key revenue and cost assumptions one at a time.
  3. Watch the formulas, revenue, cost, profit and cash update immediately. Profit is above the zero line; loss is below it.
  4. Save Plan A, create Plan B, and compare the two choices.
  5. Generate a personal report showing your choices, results and open questions.

Try an experiment

Choose a business and a question, make a prediction, then compare the low, medium and high cases. Use at least one number from the chart to explain what changed.
