    Addition of two 8 bit numbers.
    Code:
       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
    Code:
       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
    Code:
       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.

    I would suggest you couple of things.

    1. Dont jump into some thread without any context as that will take longer for you to make someone understand what you are looking for.
    2. We are not here to complete your assignments but its you who need to be doing that. Its just that we can assist you.

    Also Please go through [thread=168]this[/thread].
