How it works
Limit
Pick a fighter, choose Limit, and trust your numbers. The faster and cleaner you solve, the harder you hit — from gentle early grades all the way to Olympic-level challenges.
A limit asks where a function is HEADED as x creeps toward a value — the height it's aiming for.
When the function is well-behaved, you can just plug the value in. lim(x→2) of (x² + 1) = 2² + 1 = 5. Substitute and evaluate.
Type the value it approaches.
