Solution - Long subtraction
230.02
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | ||
| . |
Put zeros in the blank number places:
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| . |
2. Subtract the numbers using long subtraction method
Subtract the numbers in the hundredths column from the top number:
2-0=2
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| . | 2 |
Subtract the numbers in the tenths column from the top number:
6-6=0
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| . | 0 | 2 |
Subtract the numbers in the ones column from the top number:
8-8=0
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| 0 | . | 0 | 2 |
Because the upper digit (2) in the tens column is too small to get a positive difference, borrow 1 from the digit (3) in the next number place which becomes (2) and get (12).

| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| 0 | . | 0 | 2 |
Subtract the numbers in the tens column from the top number:
12-9=3
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 12 | |||||
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| 3 | 0 | . | 0 | 2 |
Write 2 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths |
| 2 | 12 | |||||
| 3 | 2 | 8 | . | 6 | 2 | |
| - | 9 | 8 | . | 6 | 0 | |
| 2 | 3 | 0 | . | 0 | 2 |
The solution is: 230.02
