The calculators on primarycalculator.com were grouped into 8 sections; starting from simple calculations (addition, subtraction, multiplication and division) to the more advanced calculations (fraction, percentage, binary and the calculations of trigonometry). All of the calculator scripts and design are developed in-house, as we aim for the best outcome in terms of performance and looks. All of the calculator functions are based on well known functions that the basic calculators provide, but with the upgrade in design and performance to minimise the learning process and maximise the benefit of the calculator.

Each calculator with individual functions also comes with a calculating history to help further navigating your calculations.
