2000 to AFFF is 36K

6000 to DFFF is 32K

3000 to EFFF is 48K

How do I calculate this information?

 

1xxx = 4K

2 to A is 9. So 9*4=36K

How do I calculate this information?

You can't calculate it unless you know how much memory each address accesses.

 

can you explain this? "2 to A is 9"

2 to A isn't 9. But your addresses don't stop with A000, do they?

First work with something that is more familiar to you.

You have a bunch of boxes, each of which contains 4 envelopes. The boxes are numbered consecutively from 2000 to 7999 (in base-10). How many envelopes are there?

First, how many boxes are there?

What would you say to someone that took your answer and asked you to explain how 2 to 7 is 6?

 

Simple.

Convert the hex values to decimal. Do the subtraction and then add 1. Finally, divide by 1024.

For example,

0000 = 0
FFFF = 65535

FFFF - 0000 = 65535 - 0 = 65535
Add 1 gives 65536
Divide by 1024 gives 65536/1024 = 64K
