Arithmetic Guru already ships a browser solver. The next product is bigger: printable books that work as direct PDF sales, print-on-demand editions, and school/distributor titles, all with a matching web page that can mark a student's answer sheet from a phone or computer.
Start with one sample book
- Download the current printable smart-book sample as a PDF.
- Use the same page design for paid packs and future POD editions.
- Keep the browser marking flow attached to every page via QR metadata.
Print on Demand
Books can carry QR-linked metadata so the printed edition still connects back to the marking site.
School Edition
Batch scanning, student tracking, and custom follow-up worksheets become the high-value institutional offer.
The Arithmetic Guru game has lots of names. It's the numbers round from Letters and Numbers, it's similar to 4 4's, sometimes it's just called an arithmetic puzzle.
You are given a few numbers and a target number. Your goal is to use any arithmetic operators on your starting numbers to create an arithmetic expression that equals the target number.
Some variants of the game let you use square-roots, exponentiation, factorial, floor and many other mathematical operations.
The Arithmetic Guru solver tries every possible arithmetic operation in the basic version and therefore comes up with every possible answer.
