There is an error in the first example problem. 3^5 is calculated incorrectly (should be 243 instead of 273).
In this lesson, we learn about bases and how to convert between different bases, such as binary and base 10. The base is the number that is being multiplied and raised to an exponent, while the exponent tells you how many times to multiply the base. We also learn how to interpret numbers written in different bases and how to convert them to base 10 by multiplying the digit in each spot by the value of that spot and adding them together. Finally, we learn that there are 10 digits in base 10, but other bases can have fewer or more digits, and may even use letters to represent values.
An explanation of how bases (ie: Base 10, Base 2 / Binary) work, how to convert between bases, and how to interpret numbers written in different bases.
