About us
We build small, trustworthy math tools that respect your time and privacy.
Adding Fractions Calculator exists for one job: help you add two fractions quickly, with readable steps and honest limits. We do not ask for accounts, and we do not send your inputs to a server.
Whether you are checking homework, adjusting a recipe, or teaching common denominators, the goal is the same: correct arithmetic, plain language, and a layout that works on a phone first.
- Mobile-first layout with high-contrast, cinematic styling
- Simple and mixed-number inputs on the same page
- Instant reduced answers with optional mixed-number display
