Code:

org 100h
.stack 100h

.code
main proc
    mov ah,01     ;taking input that save in ax(al)
    int 21h

    ;now move value of ax into bx to get another value
     mov bx,ax

    ;now again gat a number
    mov ah,01
    int 21h

    ;subtract 2nd number from first number result is save in bx
    sub bx,ax

    ;code for print newline
    mov dx,10
    mov ah,02
    int 21h
    mov dx,13
    mov ah,02
    int 21h

    ;now display the result 
    mov dx,bx

    ;now there is an assci value in bx
    ;so get a real number we add 48 into result that is 0
    add dx,48
    mov ah,02
    int 21h
