Addition of two 8 bit numbers.

   MVI B, 06
   //Load Register B with the Hex value 06
   MOV A, B
   //Move the value in B to the Accumulator or register A
   MVI C, 07
   //Load the Register C with the second number 07
   ADD C
   //Add the content of the Accumulator to the Register C
   STA 8200
   //Store the output at a memory location e.g. 8200
   HLT
   //Stop the program execution

Addition of two 8 bit numbers stored in memory

   LDA 8500
   //Load the accumulator with the address of memory viz 8500
   MOV B, A
   Move the accumulator value to the register B
   LDA 8501
   //Load the accumulator with the address of memory viz 8501
   ADD B
   //Add the content of the Accumulator to the Register B
   STA 8502
   //Store the output at a memory location e.g. 8502
   HLT
   //Stop the program execution

Addition of two 8 bit numbers stored in memory and storing the carry

   LDA 8500
   //Load the accumulator with the address of memory viz 8500
   MOV B, A
   Move the accumulator value to the register B
   LDA 8501
   //Load the accumulator with the address of memory viz 8501
   ADD B
   //Add the content of the Accumulator to the Register B
   STA 8502
   //Store the output at a memory location e.g. 8502
   MVI A, 00
   //clear the accumulator with 00
   ADC A
   //Add with carry the content of the accumulator
   STA 8503
   //Store the output at a memory location e.g. 8503
   HLT
   //Stop the program execution

Implementing the above program for the subtraction is very simple just replace ADD with SUB and ADC with SBB and all should be working fine.

can u help n explain 2 me to write 8085 instruction for this program?

Write 8085 ALP to convert the given binary number in a memory location X to the equivalent unpacked BCD numbers in three consecutive memory location
