1st you need to take the 2 and add it with the 0, So Its 2+0=2 the you put a 2 under the line.
Then you need to move over to the 1 and since there isnt anything under it you just bring the 1 down.

you add each place value. you have to line up the numbers. You can think of 2 as 02. We just don't write 0 in front of numbers because it is pointless.
