What is the Syntax for Get Value?

There is no "get" keyword. In Lua, it's very close to how Java does it. You can:

1. Assign 1+ expressions to 1+ variables: a, b = 1+2, "hello" --'a' will be 3, 'b' will be "hello"; more common is just one variable: c = workspace.MyPart
2. Pass the expression(s) to a function: doSomething(a, 20)

Note that in Java, you have to declare the type of the variable, but in lua you don't. The closest thing is that you can specify that a variable is local, like so: local a, local a, b, c, or even local a, b = 1+2, "hello"

By the way, you can send or receive multiple arguments to a function:

function receiveMultiple(a, b)
	print(a, b)
end
receiveMultiple(1, 10) -- will print 1, 10
function receiveAnyNumber(...)
	local list = {...}
	for i = 1, #list do
		print(list[i])
	end
end
receiveAnyNumber() -- will not print anything
receiveAnyNumber(1, 2, 4) -- will print 1 then 2 then 4
function returnMultiple()
	return 1, 2
end
print(returnMultiple()) -- will print 1, 2
a, b = returnMultiple() -- a will be '1', b will be '2'
