Homework Equations
The Attempt at a Solution
I know there is just some really obvious way to do it. It was only worth 2 marks. Checking the answer on a calculator it was 33340000 and 6667-3333=3334 so i wasnt sure if that was how you did it, found the answer to the integers minus each other and add zeros. But i tried other examples and it didnt hold true.
Thanks
