simple calculator for arm assembly?

I need a simple calculator, that will simply do addition from input numbers and the expression and show the answer, all done in a console window like UART#1 but I am at a complete loss. I missed a lot of lectures due to personal issues and cannot get the lecture notes till end of term.

I was given this code to start with if it gives some idea.

IMPORT getkey
IMPORT sendchar
EXPORT start


; Read a sequence of ASCII character codes from UART #1 until
; the user enters a "+" character
BL getkey ; while (read next ASCII character c
BL sendchar ; display ("echo") character c
CMP R0, #'+' ; continue while c not "+")
BEQ endwh1 ; {

; You can process the ASCII charcater code stored in R0 here!!

B while1 ; } branch back to read next character

; The rest of your program (e.g. reading the second sequence of digits)
; goes here!!

stop B stop
