Find Matrix Rank ...
`[[1,1,1],[-1,-3,-3],[2,4,4]]`

Solution:
 Rank 
`1``1``1`
`-1``-3``-3`
`2``4``4`


Now, reduce this matrix
interchanging rows `R_1 harr R_3`

 = 
`2``4``4`
`-1``-3``-3`
`1``1``1`


`R_1 larr R_1-:2`

 = 
`1``2``2`
`-1``-3``-3`
`1``1``1`


`R_2 larr R_2+ R_1`

 = 
`1``2``2`
`0``-1``-1`
`1``1``1`


`R_3 larr R_3- R_1`

 = 
`1``2``2`
`0``-1``-1`
`0``-1``-1`


`R_2 larr R_2-:-1`

 = 
`1``2``2`
`0``1``1`
`0``-1``-1`


`R_3 larr R_3+ R_2`

 = 
`1``2``2`
`0``1``1`
`0``0``0`


The rank of a matrix is the number of non all-zeros rows
`:. Rank = 2`
