  3. 3. If a row doesn’t consist entirely of zeros, then the first non zero number in the row is a 1. We call this as leading 1. If there are any rows that consist entirely of zeros , then they are grouped together at Bottom of the matrix. In any two successive rows that do not consist entirely of zeros, the leading 1 in the lower row occurs farther to the right than the leading 1 in the higher row. Each column that contains a leading 1 has zeros everywhere else in that column. Reduced Row Echelon Form Gauss Jordan Gauss Jordan
