 ## Calling Functions

 Besides function calling with round parens, Mondo Notation has a lot in common with Mini Notation:
 
+### Brackets
+
 - `[]` for 1-cycle sequences
 - `<>` for multi-cycle sequences
 - `{}` for stepped sequences (more on that later)
+
+### Infix Operators

 - \* => [fast](/learn/time-modifiers/#fast)
 - / => [slow](/learn/time-modifiers/#slow)
-- , => [stack](/learn/factories/#stack)
 - ! => [extend](/learn/stepwise/#extend)
 - @ => [expand](/learn/stepwise/#expand)
 - % => [pace](/learn/stepwise/#pace)
 - ? => [degradeBy](/learn/random-modifiers/#degradeby) (currently requires right operand)
 - : => tail (creates a list)
 - .. => range (between numbers)

 here we can see much we can save when there's no boundary between mini notation and function calls!
 
+### Chaining Infix Operators
+
+Infix operators exist as regular functions, so they can be chained as well:

+In this case, the \*2 will be applied to the whole pattern.

 ### Lambda Functions
 
 Some functions in strudel expect a function as input, for example:
