As Scratch is a GUI based programming language, here is the key for the symbol usage in the lists:
* <=> - Hexagonal Box, requiring that one of the following pieces be entered:
** <()<()> - Returns true if Number 1 is less than Number 2
** <()=()> - Returns true if Number 1 is equal to Number 2
** <()>()> - Returns true if Number 1 is greater than Number 2
** <<=>and<=>> - Returns true if Statement 1 AND Statement 2 both return true
** <<=>or<=>> - Returns true only if Statement 1 OR Statement 2 returns true
** <not<=>> - Returns true if Statement returns false, and vice versa
* () - Circular/Oval Box, requiring that one of the following pieces be entered:
** 4 - Any number
** (Num) - Any variable
** (pick random () to () ) - Self explanatory
** (join [=]|[=]) - Joins two Strings
** (letter()of[=]) - Returns character number () of string [=]
** (length of[=]) - Gets the length of the string
** (()mod()) - Gets the AbsoluteValue of Num1-Num2
** (round()) - Rounds the number to the nearest integer
** ([list v] of ()) - Does the task specified to the number given.
*** abs - AbsoluteValue
*** sqrt - SquareRoot
*** sin - the Sine of a number
*** cos - the Cosine of a number
*** tan - the Tangent of a number
*** asin - the Arcsine of a number
*** acos - the Arccosine of a number
*** atan - the Arctangent of a number
*** ln - HelpMe
*** log - HelpMe
*** e ^ - e to the power of...
*** 10 ^ - number of zeros you wish to shove on the end of 1
