ond, unlike the numerical approximations generated by a computer,
algebraic answers are exact. The third and perhaps the most important
advantage is that the goals of scientific investigation are often better
served by a result in algebraic form.
The algebra developing history shows that algebra is gradually
transforming in many other branches of science that have their own
direction.
