# notes from eris' k class

operator precedence: always from right to left.

types:

- integer (list of)
- float (list of)
- character (list of/string)
- dictionary (list of/table)
- symbol (list of)

lists are enclosed between parenthesis, and items separated with semicolons

(1;2;3) ("a";"b";"c")

equivalent to:

1 2 3 "abc"

assignment is done with :

a: 1 b: 1 2 3

## verbs

minus sign (-), unary is negate, binary is subtraction:

- 1 2 3 result -1 -2 -3 2 - 1 result 1

plus sign (+), binary is addition:

1 + 2 result 3

asterisk (*), unary is "first", binary is multiplication

2 * 3 result 6 * 3 2 1 result 3

vertical bar (|), unary is reverse, binary is mod?

|1 2 3 result 3 2 1

with colon (:) one can force the use of the unary mode, e.g.

*: 3 2 1

exclamation mark (!) applied to an integer produces the natural numbers from 0 to that integer minus one:

!5 result 0 1 2 3 4

percent sign (%) is division
