How do I fix "Position is not a valid member of Workspace"?

I'm currently learning scripting and so how do I fix this?

myvariable = 10

if (myvariable == 10) then  -- Brick Movement and Properties
	
	game.Workspace.Brick.BrickColor = BrickColor.new("Bright red")
	game.Workspace.Brick.Anchored = true
		
	game.Workspace.Brick.Position = Vector3.new(0,10,0)  
print("Sucsess")
	
end

function MoveBrick (name) -- Move Brick
	game.Workspace.Position = game.Workspace.Brick.Position + name
end

function Calculation (number1,number2) -- Calculation
	local result = number1 + number2
	return result
	end

MoveBrick (Vector3.new (5,0,0))
CalculationResult1 = Calculation (6,2)
CalculationResult2 = Calculation (40,29)
print(CalculationResult1)
print(CalculationResult2)       

that script is just a jumled mess- nobody will be able to fix that.....
