Explain what can happen if you line up the digits incorrectly when you rewrite addition problems

If you line up digits incorrectly when you rewrite addition problems, you can get the wrong answer. say we have 567 + 43.

  567
+
    43

if you line them up correctly like so, you get 610.

however, if we use the incorrect lining, we get

   567
+
   43 

which would give us 997.

hope it helps!
