This online calculator solves systems of linear equations using row reduction (Gaussian elimination) while retaining fractions on all calculation stages. At the end, it returns the results in two forms - as a floating point numbers and as a fractions (with numerator and denominator)

The calculator takes the equation of a circle in general form, with variables for x, y, and constants a, b, c, d and e, and converts it to the standard form equation for a circle with variables h, k, and r. It then calculates the center of the circle (h, k) and its radius r. If the equation cannot be converted to standard form, the calculator reports an error message.

This generator allows you to load an OpenOffice document with data, a document template, and generate a final document based on the data and the template. For example, a data document may contain a list of event attendees, a template document may contain an invitation card template, and the final document will contain invitation cards for all attendees from the list.
