How to display the result on the screen?

Question

assembler

Hello! I started to master NASM and now I tried to parse the first program:

section .text
global _start
_start:
mov     ax,     8
mov     cx,     6       
mov     dx,     cx      
add     dx,     ax
 
; sys_exit
mov eax, 1
mov ebx, 0
int 0x80

How to display on the screen?
Thank you.

There are no magical printf()
1) Convert the numeric value to text. For this, you decided to study AFM in order to stretch your brain.
2) Glue some pre-prepared text with the text from the previous one in a new buffer, if necessary.
3) Call a system call to display the prepared buffer with text on the screen.
