Some Math Reminders:

The caret sign ^ is a way to show (using ASCII) that 
you've raised a base number to an exponent.


Kilobyte is 2^10, or  1024^1, or              1024 bytes
Megabyte is 2^20, or  1024^2, or         1,048,578 bytes
Gigabyte is 2^30, or  1024^3, or     1,073,741,824 bytes
Terabyte is 2^40, or  1024^4, or 1,099,511,627,776 bytes


When you multiply two numbers, if they are raised to an exponent but
have the same base, you can simply add the exponents. 

For example:

  2^4 * 2^6 = 2^10 = 1 Kilobyte

  32K = 2^8 * 2^10 = 2^18  = 262,144 bytes
