Problem
1. Write an instruction sequence to decrement the contents of data memory locations 0x10, 0x1 1, and 0x12 by 5, 3, and 1, respectively.
2. Write an instruction sequence to add the 3-byte numbers stored in memory locations 0x1 1-0x13 and 0x14-0x16 and save the sum in memory locations 0x20-0x22.
3. Write an instruction sequence to subtract the 4-byte number stored in memory locations 0x10-0x13 from the 4-byte number stored in memory locations 0x00-0x03 and store the difference in memory locations 0x20-0x23.
