## Worksheet Description

This worksheet is a collection of exercises designed to challenge students with mathematical problems that involve the manipulation of numbers expressed in scientific notation. Each task presents a pair of numbers that students must combine by applying specific arithmetic operations. The emphasis is on maintaining the proper format of scientific notation throughout the process. It is important for students to keep track of both the magnitude and the exponents as they work through the problems.

The primary aim of this worksheet is to reinforce the students’ understanding of scientific notation, a method of writing very large or very small numbers concisely. Through repetitive practice, the worksheet encourages the development of accuracy and efficiency in performing operations with exponents. It guides students to pay attention to detail and to follow mathematical procedures correctly. The ultimate goal is to instill confidence and competence in handling complex numerical expressions that are commonly encountered in advanced math and science courses.
