Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | |||||||
| . |
Put zeros in the blank number places:
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the thousandths column from the top number:
2-0=2
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| . | 2 |
Subtract the numbers in the hundredths column from the top number:
0-0=0
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| . | 0 | 2 |
Subtract the numbers in the tenths column from the top number:
1-0=1
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| . | 1 | 0 | 2 |
Because the upper digit (0) in the ones column is too small to get a positive difference, borrow 1 from the number to the left (20) which becomes (19) and get (10).
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| . | 1 | 0 | 2 |
Subtract the numbers in the ones column from the top number:
10-4=6
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| 6 | . | 1 | 0 | 2 |
Subtract the numbers in the tens column from the top number:
9-6=3
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| 3 | 6 | . | 1 | 0 | 2 |
Write 1 in the hundreds place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| 1 | 3 | 6 | . | 1 | 0 | 2 |
Write 5 in the thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| 5 | 1 | 3 | 6 | . | 1 | 0 | 2 |
Write 1 in the ten thousands place.
| Place value | ten thousands | thousands | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 1 | 9 | 10 | |||||||
| 1 | 5 | 2 | 0 | 0 | . | 1 | 0 | 2 | |
| - | 6 | 4 | . | 0 | 0 | 0 | |||
| 1 | 5 | 1 | 3 | 6 | . | 1 | 0 | 2 |
