Implied Multiplication

If no operator is specified between 2 values, the values are multiplied.
Example: is equivalent to 2 ∙ π

Between variables, a space must be set. Example: 2π f is interpreted as 2 ∙ π ∙ f

If there are no spaces between a and b, this is considered a variable named ab.

After leading digits, space is not required because names must always begin with letters. The term 123a can therefore be clearly recognized as 123 ∙ a
