Arithmetic as variable?
I have function in which perform arithmetic on standart numbers.
function arithmetic(formula)
x = 1
y = 10
z = formula
print(z)
end
arithmetic(x+y)
The problem is: it starts to count in function variables, when x and y are nil, and error happens because x and y are nil at the first line.
So i want to perform arithmetic only when i want to, in this case only on line 4.

x & y are not defined globally in the script in line 8. When you're calling a function, it takes in arguments for the function to play with.
function Arithmetic(x, y) -- Parameters for arguments
local Solution = x + y
print(Solution)
end
-- At this point, the function is defined; the output will spit out the solution when it is called.
Arithmetic(1, 10) -- Here, the defined function "Arithmetic" is called, taking 1 and 10 for x and y respectively.
