Deleted lines 4-6:

So why would one *want* to enter numbers in another base? Often it is convenient to enter numbers in binary form if they are being used to set port variables. This often corresponds to setting one pin HIGH and another LOW, for example.

Numbers are sometimes entered in hexidecimal to save characters in entering larger numbers. This is something that comes with practice to programmers but is often confusing to beginners.

So why would one *want* to enter numbers in another base? Often it is convenient to enter numbers in binary form if they are being used to set port variables. This often corresponds to setting one pin HIGH and another LOW, for example.

Numbers are sometimes entered in hexidecimal to save characters in entering larger numbers. This is something that comes with practice to programmers but is often confusing to beginning programmers.
