Reduced row echelon form
Reduced row echelon form is the matrix arrived at
after back substitution is continued further to produce zeros [where?].
From reduced row echelon form of a matrix \( A \), it is easy to calculate [what aspect of \( A \)?].
Can you remember their form? On the reverse there are two examples.
