  problem of Subtraction. Multiplication.
  Addition and division.

Hybrid Computer: 

• The Hybrid computers have best combined
  features of both Analog and Digital components in
  hybrid computer user can process both Analog
  (continuous) and Digital (discrete) data. It is used
  for scientific problems. 

• Mostly used Scientist
  •Both capabilities of Analog & Digital are available
  in this computer
