Solution - Long subtraction
3.56
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | tens | ones | . | tenths | hundredths |
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (4) in the hundredths column is too small to get a positive difference, borrow 1 from the digit (9) in the next number place which becomes (8) and get (14).
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 14 | ||||
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| . |
Subtract the numbers in the hundredths column from the top number:
14-8=6
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 14 | ||||
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| . | 6 |
Subtract the numbers in the tenths column from the top number:
8-3=5
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 14 | ||||
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| . | 5 | 6 |
Subtract the numbers in the ones column from the top number:
8-5=3
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 14 | ||||
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| 3 | . | 5 | 6 |
Subtract the numbers in the tens column from the top number:
5-5=0
| Place value | tens | ones | . | tenths | hundredths |
| 8 | 14 | ||||
| 5 | 8 | . | 9 | 4 | |
| - | 5 | 5 | . | 3 | 8 |
| 0 | 3 | . | 5 | 6 |
The solution is: 3.56
