I have a project that I need to create a program in assembly language that will perform addition, subtraction, multiplication and division of base 7 to base 9. I have no idea on this as I'm a beginner in assembly language. My main problem on this is that I don't know how to perform basic calculator operations by coding in assembly language. Hope you can help me with this. At least an idea on how to perform calculation will help.
What I have tried:
abase7 db 0dh,0ah,'Base 07 Addition$'
ad db 0dh,0ah, 'Addend(00-99): $'
au db 0dh,0ah, 'Augend(00-99): $'
sum db 0dh,0ah,'The sum is : $'
mov dx,offset abase7
mov dx,offset ad
mov dx,offset au
mov dx,offset sum
