1. Using the given table from the module, we can see the conversion:
3 A E
162 161 160
256 16 1
(3 x 256) + (10 x 16) + (14 x 1) = 942
Therefore, 3AE = 942.
Example: Convert Hexadecimal --> Binary
If headecial # is 3AE…
1. Using the given table from the module, and working from right to left, we can see the conversion:
3 A E
0011 1010 1110
Therefore, 3AE = 001110101110.
Example: Convert Binary --> Hexadecimal
