binary shift

• if you shift to the left you multiply

  if you shift to the right you divide
• a bit can be either 0 or 1
• binary numbers are made up of combinations of these two digits (0's and 1's)
• binary is base two, decimal is base ten
• a binary digit is called a bit
• 2= move 1 space

  4= move 2 space

  8=move 3 space

  16=move 4 space

  ect
• • 1 left shift multiplies by 2 (10^2) 
  • 2 left shifts multiply by 4 (100^2) 
  • 3 left shifts multiply by 8 (1000^2) 
  • 4 left shifts multiply by 16 (10000^2) 
• 
  

  • 1 right shift divides by 2 (10^2) 
  • 2 right shifts divide by 4 (100^2) 
  • 3 right shifts divide by 8 (1000^2) 
  • 4 right shifts divide by 16 (10000^2) 
• left shifting moves the bits to the left and fills the empty spaces with zeros on the right side.
• right shifting moves the bits to the right and fills the empty spaces with zeros on the left side.
