To solve an equation, move a term across the equals sign and flip its sign at the same time — that is transposing, and it works because of the properties of equality: do the same thing to both sides. Tap a number card and watch it fly over the equals sign and turn into the opposite sign; then combine, scale the coefficient to 1, and reshape the equation into x＝a step by step.
Equation terms become cards: tap a number card and watch it fly across the equals sign while its sign flips (transposing flips signs); then combine, and scale the coefficient to 1, step by step until x＝a. Covers x＋a＝b, x−a＝b and ax＋b＝c with randomized rounds.
