Every Transaction Has Two Sides
Transaction analysis: what changes, by how much, and why the equation still balances.
"Every transaction changes at least two accounts, and the equation balances after each one."
A short lesson, then a quiz. ❤️×3 — a wrong answer costs a heart; finish with at least one left and the level is yours. Lose all three and you'll have to try again. Replay any time — XP and cleared levels are never lost.
