Question

Do you think adding, subtracting, multiplying, or dividing numbers written in scientific notation is easiest? Why?

Answer 1

Adding and subtracting numbers written in scientific notation is generally considered to be the easiest. This is because when adding or subtracting numbers in scientific notation, you only need to focus on manipulating the powers of 10, while keeping the base numbers the same. By aligning the powers of 10, you can easily perform the addition or subtraction of the coefficients.

Multiplying and dividing numbers in scientific notation require more steps and calculations. When multiplying, you multiply the coefficients and add the exponents, while when dividing, you divide the coefficients and subtract the exponents. These additional steps can introduce more potential for errors and make the process more complex and time-consuming compared to addition and subtraction.

However, the perception of which operation is easiest may vary from person to person, as some individuals may find multiplication or division in scientific notation more intuitive or simpler for their own mathematical skills and understanding.
