Explain one way to add 3 digit numbers

I am going to give an example then explain how I added it. :)      Ok, so say you have to

                           11

add 246+396      246

                         +396  so first add 6 +6you get twelve. And because it is a double digit, you put the          642   under the 6 and then the one over 4. Next add 4+9+1...you get 14 so you would do the same as you did with 12 but instead with the new sum..14.  Now you have to add 2+3+1 which is 6...and because it is a single digit, you place it under the 3 and get you answer of 642. 

So I added this by starting on the last number and adding from right to left by one set of numbers at a time I hope this helps!
