title: How to produce double digits numbers LC3
body: <p>Having trouble printing any number past 10 in my LC3 program to multiply 2 input numbers to get a area. It works for any numbers below 10 so I know my multiplication is right. The problem is it produces weird symbols or nonsense anywhere higher then 10. So confused why. Here is my code:</p>
  
  <pre><code>.ORIG x3000
  
  AND R3, R3, #0
  
  AND R4, R4, #0
  
  LD R5, INVERSE_ASCII_OFFSET
  
  LD R6, DECIMAL_OFFSET
  
  ;---------------------
  
  ;receiving length
  
  LEA R0, PROMPT1 ;load the address of the 'PROMPT1' message string
  
  PUTS ;Prints PROMPT1
  
  GETC ;get length
  
  ADD R1, R0, #0
  
  ADD R1, R1, R5
  
  ;receving width
  
  LEA R0, PROMPT2 ;load the address of the 'PROMPT2' message string
  
  PUTS ;Prints PROMPT2
  
  GETC ;get width
  
  ADD R2, R0, #0
  
  ADD R2, R2, R5
  
  ;----------------------
  
  ;MULTIPLICATION to find AREA
  
  ADD R4, R2, #0
  
  FINDAREA:
  
                 ADD R3, R3, R1
  
                 ADD R4, R4, #-1
  
                 BRp FINDAREA
  
  LEA R0, PROMPT3
  
  PUTS
  
  ADD R0, R3, R6
  
  OUT
  
  HALT
  
  PROMPT1 .STRINGZ "ENTER LENGTH OF THE RECTANGLE:"
  
  PROMPT2 .STRINGZ "ENTER WIDTH OF THE RECTANGLE:"
  
  PROMPT3 .STRINGZ "AREA OF THE RECTANGLE:"
  
  INVERSE_ASCII_OFFSET .fill xFFD0
  
  DECIMAL_OFFSET .fill #48
  
  .END```
