Spiegazione passo passo

1. Rewrite the numbers from top to bottom, aligned by their place values

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	2	3	0	0	0	0	0	0
-					4	0	0	0

2. Subtract the numbers using long subtraction method

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	2	3	0	0	0	0	0	0
-					4	0	0	0
								0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	2	3	0	0	0	0	0	0
-					4	0	0	0
							0	0

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

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones

	2	3	0	0	0	0	0	0
-					4	0	0	0
						0	0	0

Because the upper digit (0) in the thousands column is too small to get a positive difference, borrow 1 from the number to the left (300) which becomes (299) and get (10).

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
						0	0	0

Subtract the numbers in the thousands column from the top number:
10-4=6

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
					6	0	0	0

Write 9 in the ten thousands place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
				9	6	0	0	0

Write 9 in the hundred thousands place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
			9	9	6	0	0	0

Write 2 in the millions place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
		2	9	9	6	0	0	0

Write 2 in the ten millions place.

Place value	ten millions	millions	hundred thousands	ten thousands	thousands	hundreds	tens	ones
		2	9	9	10
	2	3	0	0	0	0	0	0
-					4	0	0	0
	2	2	9	9	6	0	0	0

The solution is: 22,996,000
