Mathematics is the study of quantity, structure, space, and change. Mathematics seeks to identify quantified repeatable action or configuration in every object and situation and underpins modern science. Mathematics is an everyday part of our lives from childhood to our senior years. Mathematics helps us to understand problems in a logical way that we can clearly communicate, whether it is the number of objects or the volume, shape or size of an object.

iCalculator Mathematics Calculators are regularly updated to include new features and facilities to help children and adults understand and calculate specific math formulae. We have calculators which calculate volume, area and specific equations.

All the Mathematics calculators featured on this site are free to use. The calculators are designed to be used online, if you do experience difficulties or you're looking for a calculator which isn't featured, please contact us. We are always looking for new projects and ideas, so are happy to receive your feedback and wish lists.
