Learn Explore pricing, costs and uncertain demand in fictional markets.
Start with everyday situations, predict an outcome, and test your ideas. You need basic arithmetic, percentages and graph reading; explanations introduce additional ideas where needed. No coding or account is required. Every investigation has school, college and workplace extensions—you can choose any of them.
Build a cash budget, trace borrowing, compare unit economics and uncertain stock, inspect incentives and evaluate a fictional investment with stated assumptions.
Open any topic directly. Review functions and graphs whenever useful.
The original two-investigation starter remains available. Choosing the full course adds its published lessons to your selected scope; your earlier work stays saved. Skipping does not count as completion or understanding.
Free exploration: no completion scope selected yet. Project reports and independent evidence are tracked separately.
Choose a unit, then open a lesson on its own page. This outline lists the sequence; it does not combine the full lessons into one page.
Track the lowest cash balance and distinguish payments, interest and remaining debt.

Can a plan with ordinary monthly surplus still run out of cash?
An original fictional budget starts with 100 credits. Income, fixed spending and variable spending recur for three months; an extra expense arrives in month two.

When does making a payment still leave more debt?
An original fictional loan applies a monthly interest rate to the opening balance, then takes a payment capped at the amount owed. No fees or annual-rate conversion is hidden.
Separate revenue from profit, manage demand scenarios and inspect incentive effects.

Does the price with highest revenue also give highest profit?
An original synthetic market buys 100 − 5 × price units, floored at zero. All money uses fictional credits. Change price and costs to inspect a business model, not a real investment.

How do overstock and missed sales pull a decision in opposite directions?
A fictional stall buys items for 4 credits, sells them for 8, and recovers a selectable salvage value for leftovers. Choose a stock order, then test multiple demand scenarios.

Can rewarding output increase defects and reduce business value?
Two authored production plans produce 40 units with 2 defects or 60 with 15. Good units earn 8 credits, all units cost 2, and defects incur a repair cost. A bonus pays per produced or accepted unit.
Discount cash flows consistently and stress-test a model-based project recommendation.

Can a project repay its cost yet have negative discounted value?
A fictional equipment project costs money now and returns equal year-end benefits. Discounting converts future credits to comparable present credits.
Plan a small fictional service or shop. Compare two price/stock choices, prepare a cash reserve, and evaluate a proposed equipment investment. Include a downside demand case and distinguish worker incentives from the business objective.
Save a report, compare captured evidence, and attempt three new cases. A completed report records submitted work; the rubric supports a separate human review of its quality.
