Latest news, features, and announcements from Nabla HQ.
Apologies for the recent downtime. We ran into some unexpected DNS issues that made the website unreachable for a while, but everything is now fully resolved and running smoothly.
On a positive note, we used the time to deploy a brand new feature: the Problem of the Day. You can now log in every day to tackle a specifically selected challenge and earn bonus XP.
Thank you for your patience, and happy problem-solving!
Great to have you here. Nabla is our new platform for anyone who wants to put their analytical skills to the test.
Whether it's combinatorics, linear algebra, or abstract number theory – you'll find challenges ranging from Level 1 (Rookie) to Level 5 (Grandmaster). Solve math problems, earn XP, and track your skill progression live on your dashboard.
Our backend evaluates your inputs symbolically. That means you can type formulas naturally, and the system will understand the underlying mathematical logic.
If you happen to spot an error in a problem or a clunky solution, just hit the report button on that specific challenge. We'll review it immediately.
Good luck and have fun solving!
