It's happening because when you run the lazyadd2 script, it is unaware of what you want the values of $num1 and $num2 to be. It is only going to know $1, $2, $3, etc. You can do this:
$ num1=1
$ num2=2
$ . lazyadd2
Or do it in the lazyadd2 script itself:
...and run it the same way you run lazyadd1 (i.e., lazyadd2 1 2).

let
let(1) User Commands let(1)NAME
let - shell built-in function to evaluate one or more arithmetic expressions
SYNOPSIS
ksh
let arg...
ksh93
let [expr...]
DESCRIPTION
ksh
Each arg is a separate arithmetic expression to be evaluated.
ksh93
let evaluates each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...)) syn-
tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.
EXIT STATUS
ksh
ksh returns the following exit values:
0 The value of the last expression is non-zero.
1 The value of the last expression is zero.
ksh93
ksh93 returns the following exit values:
0 The last expr evaluates to a non-zero value.
>0 The last expr evaluates to 0 or an error occurred.
