+-- Create a table named supermath to store our custom functions.
+local supermath = {}
+
+-- Set the metatable of supermath to the standard math module.
+setmetatable(supermath, {
+  __index = math  -- This allows supermath to access functions from the math module.
+})
+
+-- Custom function to round a number x.
+function supermath.round(x)
+  return math.floor(x + 0.5)  -- Round the number to the nearest integer.
+end
+
+-- Examples of usage:
+print(supermath.floor(2.3))  -- This calls the floor function from the standard math module.
+print(supermath.floor(2.7))  -- This also calls the floor function from the standard math module.
+
+-- Now let's use our custom rounding function.
+print(supermath.round(2.3))  -- OUTPUT: Will round to 2.
+print(supermath.round(2.7))  -- OUTPUT: Will round to 3.
