It has 2 significant branches, differential calculus (worrying rates of modification and slopes of curves), and important calculus (worrying build-up of amounts and the locations under and in between curves); these 2 branches are associated to each other by the essential theorem of calculus. Calculus has actually traditionally been called “the calculus of infinitesimals”, or “infinitesimal calculus”. The word “calculus” comes from Latin (calculus) and refers to a little stone utilized for counting.
