Video starts with review of the basics of square roots, showing symbols and how they are written. This video only covers perfect squares. Then they go through the perfect squares, from 0 to 6. Then a number of problems are done. From there they move to other problems that are not perfect squares. This information is used to solve the hypotenuse for right triangles. They give the formula and apply this to different triangles. They go on to show how to add, subtract, multiply, and dividing square roots. Video is good quality and good for all students as a review or initial learning of the topic.
