Operators	Meaning	Association
()	Parentheses
log()	Function call
34 cm , 45 cm	Unit suffix
^	Exponent	right to left
+x, -x, !x	Unary	right to left
as, in	Unit or number system conversion
*, / , mod, of	Multiplication, division, modulus and percentage	left to right
+, -	Addition and subtraction	left to right
<, >, <=, >=, <==, >==	Camparison	left to right

For general percentage operations like adding or subtracting the per cent of value, you can do 12 + 24%, 1230 - 23.23%

You can declare variables using = or : operator, you can also reassign them

please note that you can't use variable names which are being used for phrases in operations and units

radius : 20cm
PI*radius^2

You can use the default functions

abs(-23) + log(123)

you can convert one unit into another. Fcal will automatically convert units to perform operations if it's needed during conversion.
