3.3 Arithmetic Operators
The following numeric operators allow us to process numeric data stored in variables or
stated literally in the program.

If an expression contains several operators then the operators at the top will operate
first, then the next.
Order of precedance can be altered using brackets.
Example
this_variable% = (7+2) * 2
In this situation the part 7 + 2 in given greater precedance by the surrounding brackets.
The answer to this is then multiplied by the two. This gives the answer as 18.
