Subtraction up to 100 · 10 scenes · 100 tasks
EduBert joins Postman Frank on his delivery route. He helps with deliveries and explores the city — from the post office through the market, bakery, school, theater and library, to Lantern Evening in Main Square.
Frank guides the way from the post office. Grandma Sophie joins at the bakery, Officer Ann at the theater, Rocky the Raccoon in City Park, and Gustav the Pigeon at City Hall. EduBert helps them count what is left, and in the finale he leads his friends through the city.

Your child practises subtraction up to 100 across 16 task types. The City's signature is the number bond — seeing how much is left when a part goes away — joined by the number line, calculation, gap-filling, true/false, comparison, sorting and memory, plus arcade minigames: bridge building, bubble popping, a maze and catching falling numbers.
Each world teaches a different operation — pick your next one!
