WebFeb 13, 2024 · Multiply a row by any real number except 0. Add a nonzero multiple of one row to another row. Performing these operations is easy to do but all the arithmetic can result in a mistake. If we use a system to record the row operation in each step, it is much easier to go back and check our work. WebIf n = 2, then det (A) = a11a22 − 0 and hence is the product of the diagonal terms. Assume that the result holds for an n × n triangular matrix. We need to show that the same is true …
