What is the Online Calculator?
Online Calculator is a free, browser-based everyday utility for students, shoppers, office workers, and everyday users.

Start with numbers and a standard arithmetic operation; LiteTools gives you an immediate calculation shown on the page. There is no account wall, so you can open the page and begin immediately.
The workspace is designed for a focused task instead of a complicated editing suite. Use a specialist financial or scientific calculator for regulated, high-precision, or advanced functions.
