Arithmetic Operations

Various  types of arithmetic  operations like addition subtraction increment and  decrement  are performed in 8085 microprocessor. Generally in these  operations one of the two  operands is accumulator and result of operation is also  stored in the accumulator except few exceptions. And after any  arithmetic  operation is  performed flags are modified  except few  exceptions. Which flags are modified and which are not modified  is specified  with explanation of all  instruction separately.

Readers are  advised to see  changes in the flag after  each operations carefully.
