The three matrix elementary row operations (swap, scale, and add) needed in Gauss-Jordan Elimination are:
1. Switching/swapping/exchanging rows
2. Multiplying row by non-zero constant/scalar
3. Row Addition
You'll use these when solving an augmented matrix or finding the inverse of a square matrix.
