    I remember seeing a video a year or so ago on facebook that showed a method for subtraction that didnt require any borrowing. Unfortunately did not save it. Have search the internet and cant find it, there are others but none as good as I remember this one being, maybe its just my memory! Do remember trying it out to check it worked with other numbers, which is why I dont think its the ones I have seen which you can see immediately will work. Just wondering if anyone has a link to something that might fit.

    Thanks, but it’s not that one. Found that one and the one I saw was much simplier, cant believe I didn’t save it now!
