Algebra

You're seeing it when a founder backs into a hiring plan by starting with a revenue target, dividing by revenue-per-employee, and solving for headcount — treating the business as a system of equations.

You're seeing it when an investor rearranges the valuation formula — if market cap equals earnings times multiple, and you know two variables, you can solve for the third to test reasonableness.

You're seeing it when an operations manager calculates required throughput by working backwards from delivery deadlines, isolating the bottleneck variable in the production equation.

Express your key business decisions as simple equations: CAC × customers = acquisition budget; LTV / CAC = unit economics viability. Rearrange to solve for the unknown. This discipline surfaces hidden assumptions and reveals which variable you should focus on moving.

Bezos is famous for reducing complex business decisions to simple algebraic relationships. The Amazon flywheel — lower prices drive more traffic, which drives more sellers, which lowers costs, which enables lower prices — is an algebraic loop expressed in business terms. Bezos consistently forces teams to quantify relationships: if input X increases by Y, what happens to output Z? This discipline of expressing strategy as a system of variables and solving for the unknown is algebraic thinking applied at scale. For founders, the practice of writing business logic as equations — even rough ones — eliminates hand-waving and makes strategic assumptions testable.
