Operations in Scientific Notation

The video tutorial explains how to handle operations with scientific notations, focusing on making exponents equal for addition and subtraction. It covers the process of adjusting exponents by moving decimals and then performing the operations. The tutorial also addresses multiplication and division of scientific notations, highlighting the addition and subtraction of exponents.

Why is it necessary to have equal exponents when adding or subtracting scientific notations?

• To simplify the calculation process

• To ensure the numbers are in the same scale

• To avoid errors in multiplication

• To make the numbers look similar

What is the first step in rewriting scientific notations to have equal exponents?

• Add zeros to the smaller number

• Focus on the smallest exponent

• Focus on the highest exponent

• Multiply the numbers by 10
