+	6	unary	left	Unary plus (indicates that a value is positive)
-	6	unary	left	Unary minus (indicates that a value is negative)
/	3	binary	left	Division
*	3	binary	left	Multiplication
.	2	binary	left	Vector dot product
><	2	binary	left	Vector cross product
U	1.5	binary	left	Union

+	1	binary	left	Addition
,	0	binary	left	List (vector, set, point, etc.) separator

Functions

In general, functions can be used with or without parentheses. For example, cosx, cos x, and cos(x) are all equivalent. However, using parentheses makes grouping more explicit and are recommended.

Simple trig functions

• sin()
• cos()
• tan()
