... 1. All rows consisting entirely of zeros occur at the bottom of the matrix. 2. The first nonzero element of any row is 1, called a leading 1. 3. For two successive nonzero rows, the leading 1 in the upper row is farther to the left of the leading 1 in the lower row. (If we add one more condition, we ...
