Objective
         In this lesson you’ll learn how 
          to do subtraction and how to 
          solve simple equations 
          involving Base 2, 8, and 16.
         Again, it is essentially the 
          same concept as Base 10, just 
          in a different base!

        Subtraction
         In Base 10 subtraction, you use 
          a very simple process.
         Look at this problem:
             48
            -37
           = 11

             48
            -37
           = 11
         Each column is subtracted to 
          get an answer of 11…pretty 
          easy, huh?

        Subtraction, Base 10
         Now look at this problem:
           63
          -37
         In this problem, you need to 
          borrow.

        Subtraction, Base 10
           513 
           63
          -37
         Borrowing means taking a value 
          from the next column and adding 
          it to the column you need.
