Is it easier to subtract when the numbers are written above and below each other? explain why?

Usually its easier to subtract numbers written vertically because of the sheer fact that you're just taking away instead of adding on.it is also easier because by doing that you can easily borrow from the places in front of the number and rewrite without problems. It also helps keep the math more organized so that your work does not confuse you; rather than writing on left and right.
