Writing numbers in the standard and scientific notation, including negative exponents. Comparing numbers represented in the scientific notation and applying the same to real-world problems.
Mapped to CCSS Section# 8.EE.A.3
Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 times 108 and the population of the world as 7 times 109, and determine that the world population is more than 20 times larger.
