• • A binary shift is how a computer system performs basic multiplication and division
  • Binary digits are moved left or right a set number of times
  • A left shift multiplies a binary number by 2 (x2) XO
  • A right shift divides a binary number by 2 (/2) O÷
  • A shift can move more than one place at a time, the principle remains the same
  • A left shift of 3 places would multiply the original binary number by 8 (2^3)
• • to multiply by two, all digits shift one place to the left
  • to multiply by four, all digits shift two places to the left
  • to multiply by eight, all digits shift three places to the left
