Explanation:

• Hexadecimal uses digits 0-9 and letters A-F to represent values from 0 to 15.
• Decimal is the standard base-10 system (0-9).
• Binary uses base-2, representing values using only 0 and 1.

In the table:

• Hexadecimal A corresponds to Decimal 10 and Binary 1010.
• Each hexadecimal digit corresponds to a 4-bit binary group.
