Two Numbers Hexa Octal Binary Subtraction (Minus) Calculation

An online minus calculator for Hex,Binary and Octal numeral system.

Protocols of Binary Subtraction:

  • 0 - 0 = 0
  • 0 - 1 = 1 , Note: borrow 1 from the next more significant bit
  • 1 - 0 = 1
  • 1 - 1 = 0,

Binary Subtract Example

00100101 - 00010001 = 00010100         

Binary Subtract Derivation

  0  0  1 10  0  1  0  1
- 0  0  0  1  0  0  0  1
  0  0  0  1  0  1  0  0

    Binary Equivalent

  • 1 Nibble (or Nybble)  =  4 bits
  • 1 Byte  =  2 nybbles  =  8 bits
  • 1 Kilobyte (KB)  =  1024 bytes
  • 1 Megabyte (MB)  =  1024 kilobytes  =  1,048,576 bytes
  • 1 Gigabyte (GB)  =  1024 megabytes  =  1,073,741,824 bytes

  • Binary Numbering System

  • system digits:  0 and 1 (Zero and One)
  • Bit (short for binary digit):  a single binary digit
  • LSB (least significant bit):  the rightmost bit
  • MSB (most significant bit):  the leftmost bit
  • Upper Byte (or nybble):  the right-hand byte (or nybble) of a pair
  • Lower Byte (or nybble):  the left-hand byte (or nybble) of a pair
  •
