In this video we will be discussing addition and subtraction in scientific notation. Scientific notation is a mathematical expression used to represent a number between 1-10 and multiplied by 10, so you can write large numbers using less digits. When adding/subtracting expressions in scientific notation, there can can be two types of problems. One in which the value of the exponent is the same, and one is which it is different. If the value of the exponent is the same, you just add teh constants and keep the exponent the same. If different, you must change the value of one the of exponents to make them the same. Remember: larger exponents equal smaller constants, and smaller exponents equal larger constants.
