function names are always in all caps.
${FUNCTION(argument)}

_X. ;match 1 or more digits. The dot is wildcard

${EXTEN:1} ; the colon is for substrings. The one is the index of the string

Set(i=${MATH(5+5, float)})
NoOp(i) ; prints out 10.000

$[expression]

exten => 1234,1,Set(count=$[2+3])
exten => 1234,n,Set(count=$[${count} + 1])

GotoIf($[${thing}]?true:false)

${IF($["${DIALSTATUS}" = "BUSY"])}
