- Teach the method first: do the same to both sides
- The equation is a scale — tap −3 / ÷2 / −x one step at a time
- The scale wobbles then settles back level with each move
- Four levels: one-step → ×÷ → two-step → x on both sides
- Every puzzle has an integer answer (exact fraction maths)
- Or type x and press Enter
- Repeated misses → a breath + a re-teach, never a buzzer
- Delphi hosts + fills the screen on phone & desktop
✓ = done · ☐ = planned. Every game is built one step at a time like this.
