# Pivot & Gauss-Jordan Tool

Does Gaussian elimination on user-entered matrix. Allows user to perform each operation or does all operations (doesn't show each step). Allows for decimal, fraction or integer mode.

### nice way to practice the GE algorithm w/o arithmetic

The user inputs the augmented matrix of a linear system, then has several options for row reducing the matrix to find a solution to the system: the reduction can be done one row operation at a time, by pivoting on a chosen element, or by row reducing in one step. Once one masters the data entry, this is a nice way for students to practice the Gaussian elimination algorithm without doing the arithmetic.
