ZELVAREN, a Pharmacy Calculator With a Learning Mode

Field notes

The calculator explains its arithmetic rather than returning only an answer: the visible liquid-dose example lays out the ratio, cross-multiplication, and resulting 10 mL. Other modules apply weight-based dosing, days’ supply, C₁V₁ = C₂V₂ dilution, and unit conversion, while the Learning Hub supplies prefilled practice cases. History and favorites are present as workflow features, though both currently contain zero items. The page explicitly positions the project as educational and warns that results require independent clinical verification.
