Because the upper digit (2) in the ones column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (12).

Subtract the numbers in the ones column from the top number:
12-9=3

Subtract the numbers in the tens column from the top number:
1-0=1

Subtract the numbers in the hundreds column from the top number:
0-0=0

Because the upper digit (2) in the thousands column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (12).

Subtract the numbers in the thousands column from the top number:
12-9=3

Because the upper digit (1) in the ten thousands column is too small to get a positive difference, borrow 1 from the digit (2) in the next number place which becomes (1) and get (11).

Place value	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	1	11
		1	12
					1	12
	2	2	2	0	2	2
-		2	9	0	0	9
			3	0	1	3

Subtract the numbers in the ten thousands column from the top number:
11-2=9

Place value	hundred thousands	ten thousands	thousands	hundreds	tens	ones
	1	11
		1	12
					1	12
	2	2	2	0	2	2
-		2	9	0	0	9
		9	3	0	1	3

Write 1 in the hundred thousands place.
