Subtract :
2.975 from 8.23

Answer

To solve the problem of subtracting 2.975 from 8.23, we can follow these steps:

### Step 1: Align the Numbers
First, we need to align the numbers by their decimal points. We can write 8.23 and 2.975 in a column format:

```
8.230
- 2.975
```

### Step 2: Prepare for Subtraction
Since 8.23 has only two decimal places, we can add a zero to make it three decimal places (8.230). This helps us to subtract easily.

### Step 3: Subtract the Numbers
Now we will subtract starting from the rightmost digit:

1. **Thousandths place**: 0 - 5
- We cannot subtract 5 from 0, so we need to borrow from the next column. The 3 in the hundredths place becomes 2, and the 0 becomes 10.
- Now, 10 - 5 = 5.

2. **Hundredths place**: 2 - 7
- Again, we cannot subtract 7 from 2, so we borrow from the next column. The 2 in the tenths place becomes 1, and the 2 becomes 12.
- Now, 12 - 7 = 5.

3. **Tenths place**: 1 - 9
- We cannot subtract 9 from 1, so we borrow from the next column. The 8 in the units place becomes 7, and the 1 becomes 11.
- Now, 11 - 9 = 2.

4. **Units place**: 7 - 2 = 5.

### Step 4: Write the Result
Putting all the results together, we have:

```
8.230
- 2.975
--------
5.255
```

So, the answer is **5.255**.
