Homework: 1. Write a program that performs the addition of two byte sized numbers that are initially stored in memory locations 'numl' and 'num2'. The addition result should be stored in another memory location total". Verify the result using emu8086. [Hint: Use DB directive to initially store the two byte sized numbers in memory locations called *num!' and 'num2'. Also reserve a location for the addition result and call it "total"] 2. Write a program that multiplies two unsigned byte sized numbers that are initially stored in memory locations numl' and 'num2. Store the multiplication result in another memory location called 'multiply". Notice that the size of memory location multiply" must be of word size to be able to store the result. Verify the result using emu8086. 3. Write a program that calculates the factorial of number 5 and stores the result in a memory location. Verify the program using cmu8086 emulator. [Hint: Since 5! = 5x4x3x2x1, use MUL instruction to find the multiplication. Store 5 in a register and decrement the register after every multiplication and then multiply the result with the decremented register. Repeat these steps using conditional jump instruction] 4. Write program so that it asks for entering an uppercase letter and converts it to lowercase
