How it works

1. Add, subtract, multiply or divide both sides. Remove all other terms to finish with x = a number. Every step stays visible.
2. Read the explanation after each mission. Hints are always available.
3. Choose any mission or resume a local checkpoint. Progress is practice history, not a certified grade.
