pdf Adding and Subtracting in Scientific Notation - B

This worksheet provides students with structured practice adding and subtracting numbers written in scientific notation. Students solve sixteen problems involving both positive and negative exponents while expressing their answers in proper scientific notation. The activity reinforces the importance of aligning powers of ten before performing operations.

Students develop fluency with rewriting scientific notation expressions, combining coefficients, and converting answers back into standard scientific notation form. The problems include a variety of exponent combinations, requiring students to apply place value reasoning and powers of ten concepts to accurately perform calculations.

This resource works well for classroom instruction, guided practice, homework, intervention, or review of operations with scientific notation. It helps build foundational skills needed for later work involving scientific notation operations, exponential expressions, and scientific applications in middle and high school mathematics.
