Two cases

The same formula (x × y), built twice — case ① is 3×4, case ② is 5×2. The ①→② card reads the difference and the ratio.

You can change the numbers right here, but changes made here are not saved. To keep what you build, use “Open in CalcAnyway” and edit there.

Try moving it

Change y₂ from 2 to 3 — case ② reaches 15 and overtakes case ①; the Δ flips sign.
Rewrite the formula in both cases — x + y, x ÷ y, anything: the two-case shape keeps working.
