pdf Adding and Subtracting in Scientific Notation - A

This worksheet provides focused practice with adding and subtracting numbers written in scientific notation. Students learn to combine quantities expressed with powers of ten while maintaining proper scientific notation form in their final answers.

Students work with both large and small numbers as they add and subtract scientific notation expressions involving positive and negative exponents. Some problems allow students to combine coefficients directly because the exponents match, while others require rewriting one quantity with an equivalent power of ten before performing the operation.

By emphasizing both computation and proper notation, this worksheet helps students strengthen their understanding of powers of ten and develop fluency with scientific notation operations.
