In this lesson, Julie Harland teaches how to multiply numbers by negative powers of 10, which is a preparation for scientific notation. She explains that when we multiply by powers of 10 with negative exponents, we're actually dividing by a power of 10. Therefore, the answer is always a smaller number, which means we need to move the decimal point to the left. By the end of the lesson, students will learn the definition of scientific notation and how to convert a number from standard form to scientific notation.
This is preparing for an introduction to Scientific Notation. In this video, we multiply numbers by powers of 10 when the exponents are negative.
