i'm writing this program and for some reasons i got this error, here is my code

maplet_error.mw

evaluating `"myadd(1)"` produces the error: invalid input: myadd uses a 2nd argument, n, which is missing.

the second question is that my procedure only calculate any integer number from 0 to 9 , is there anyway to get this procedure

to calculate bigger...

hello everyone, this is my first time visit mapleprimes, i just started to use maplets programming, so there are a lot of things i still don't know about this maplet, if i ask some stupid questions please be patient with me.

so i've been trying to write a maplet that will calculate some simple functions such as addition, multiplication, division,...,it's kind of like a calculator. 

i've been trying all day, and no luck so far. help please.
