Quantum calculus is sometimes called 'calculus without limits' because it is equivalent to traditional infinitesimal calculus without requiring the notion of limits.
Notes on verification
Multiple independent academic sources consistently confirm both the nickname 'calculus without limits' and the technical accuracy of the claim. Sources include authoritative references (Springer textbook, Wolfram MathWorld) and peer-reviewed papers (arXiv preprints, Frontiers in Physics). All sources align on the core claim with no contradictions found.
