We need no Python programming to calculate. @QED is our new wonderful calculator.
You can get the tangent values of 1,000,000 numbers at once. Good bye spreadsheet applications, Python, R.
Easy to draw and customize charts. Without studying Matplotlib, you can create so elaborate graphs setting the color, font size and family, width, margin of all parts.
The greatest number encyclopedia all the mathematicians love.
Cut rows, add columns, sort values. @SQL is the next standard spreadsheet.
Do you want to delete extra spaces from your text? You can do it, of course.
@QED explores the universe of data and statistics such as world population, migration, crime rates, poverty rates.
