This dual representation helps in better understanding of values in different systems.

Hexadecimal Number System Explained

The hexadecimal system is a base-16 numbering system widely used in computing. Unlike the decimal system (base-10), it uses 16 symbols:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

Value Representation:

HexDecimal
A10
B11
C12
D13
E14
F15

Why Computers Use Hex:

  • Easier to read than binary
  • Compact representation of binary data
  • Used in memory addresses
  • Used in machine-level programming

Hex Calculator Formulas Explained

1. Hex Addition

Result = Hex1 + Hex2

Example:

1A3F + 0F2B = 296A

2. Hex Subtraction

Result = Hex1 - Hex2

Example:

1A3F - 0F2B = B14

If result is negative, the tool returns 0.

3. Bitwise AND Operation

Result = A & B

This compares each bit:

  • 1 & 1 = 1
  • 1 & 0 = 0
  • 0 & 0 = 0

Example:

FF AND 0F = 0F

4. Bitwise OR Operation

Result = A | B

Rules:

  • 1 | 0 = 1
  • 1 | 1 = 1
  • 0 | 0 = 0

Example:

A1 OR 0F = AF

5. Bitwise XOR Operation

Result = A ^ B

Rules:

  • 1 ^ 1 = 0
  • 1 ^ 0 = 1
  • 0 ^ 0 = 0

Example:

FF XOR 0F = F0
