A rather important part of arithmetics and algebra is the subject of powers. We already had a small introduction itno the subject of powers when dealing with squaring. The square is the simplest form of a power. In this paragraph you will be introduced into what a power is and how you do calculations with them. In video 1 we will introduce into the subject, explaining you what a power is and what the basic elements base and index are. In video 2 we will show you how to deal with powers with respect to the order of operations. Until now we only considered en discussed powers with a positive base. In video 3 we will also deal with powers with a negative base and how this influences the value of a power.
