2.2 Simple arithmetic operations

We can do other simple arithmetic:

? 7 * 52;
364
? 7 - 12;
-5 

Caution: Spaces are needed! In Dylan, it is legal to use characters such as +, -, *, <, >, and / in names of variables. Therefore, in most cases, you must leave spaces around those characters in code, to make it clear that you are using them as functions, and that they are not part of the name of a variable. For example:

a + b means add a and b.

a+b means the name a+b.

We can multiply several numbers together:

? 24 * 7 * 52;
8736
