Operations with Scientific Notation: Addition, Subtraction, Multiplication, and Division

This video tutorial by Mr. Honker covers operations with scientific notation, including multiplication, division, addition, and subtraction. It explains how to handle the powers of 10 and provides examples for each operation. The video also discusses two methods for adding and subtracting numbers in scientific notation: converting to standard form and using a common power of 10.

What operation do you perform on the powers of ten when multiplying two numbers in scientific notation?

• None of the above

• Divide the exponents

• Subtract the exponents

• Add the exponents
