Solution - Long subtraction
332.768
Step-by-step explanation
1. Rewrite the numbers from top to bottom, aligned by their place values
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| . |
2. Subtract the numbers using long subtraction method
Because the upper digit (1) in the thousandths 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 (11).
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| . |
Subtract the numbers in the thousandths column from the top number:
11-3=8
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| . | 8 |
Subtract the numbers in the hundredths column from the top number:
8-2=6
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| . | 6 | 8 |
Subtract the numbers in the tenths column from the top number:
9-2=7
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| . | 7 | 6 | 8 |
Subtract the numbers in the ones column from the top number:
6-4=2
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| 2 | . | 7 | 6 | 8 |
Subtract the numbers in the tens column from the top number:
7-4=3
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| 3 | 2 | . | 7 | 6 | 8 |
Write 3 in the hundreds place.
| Place value | hundreds | tens | ones | . | tenths | hundredths | thousandths |
| 8 | 11 | ||||||
| 3 | 7 | 6 | . | 9 | 9 | 1 | |
| - | 4 | 4 | . | 2 | 2 | 3 | |
| 3 | 3 | 2 | . | 7 | 6 | 8 |
The solution is: 332.768
