Does Google offer a math application or browser add-on?

Google does offer a math application. Under the "Home and Office" category of Google products, there is an application called Google Sheets. Google Sheets allows users to open, edit, and create interactive spreadsheets. Also, if one types "Calculator" into the Google search bar, a small calculator appears on-screen.

Google Sheets allows a user to use an interactive spreadsheet. This spreadsheet has several functions, including the ability to create graphs from raw data. The calculator application that pops up when using the Google search engine has most of the functions of a standard scientific calculator. Both applications may come in handy when working with numbers.
