Question

Develop and test an Intel 8086 assembly program by emu8086 amd dont use any extirnall lib , that reads two decimal numbers x and y. Your program
should display the result of their:
1) Addition: x+y
2) Subtraction: x-y
3) Multiplication: x*y
4) Division: x / y
Notes:
 x and y are two-digit decimal numbers (i.e. 0-99).
 The program should display an error message if the value of y is zero, in the case of division.
 You can assume only positive numbers but you will get a bonus if your program can read and handle
negative numbers.
 You will get higher mark if your program accepts only two decimal digits (0-9) for each number and
print error message when the user tries to enter non-decimal digits (e.g. A-Z, or a-z, or any special
character).
Your program output should be similar to the following examples:
Example1: (x>y)
Please enter two 2-digit decimal
number:
X= 48
Y= 26
X + Y = 74
X – Y = 22
X * Y = 1248
X /Y = 1 with Remainder 22
Example2: (x<y)
Please enter two 2-digit decimal
number:
X= 12
Y= 37
X + Y = 49
X – Y = -25
X * Y = 444
X /Y = 0 with Remainder 12
Example3: (y=0)
Please enter two 2-digit decimal
number:
X= 56
Y= 00
X + Y = 56
X – Y = 56
X * Y = 00
X /Y = error overflow
