Two word-wide unsigned integers are stored at the memory addresses 0A00 H and 0A02 H respectively, Write an instruction sequence that computes and stores their sum, difference, product, and quotient then Store these results at consecutive memory locations starting at address 0A10 H in memory. To obtain the difference, subtract the integer at 0A02 H from the integer at 0A00 H. For the division, divide the integer at 0A00H by the integer at 0A02 H. Use register indirect relative addressing mode to store the various result.
