Grade 5 Subtraction Worksheet: Subtracting Large Numbers in Columns

Let's solve each subtraction problem step by step. We'll subtract the numbers in columns, borrowing when necessary.

1. 57,644,196 – 49,732,152

```
57,644,196
- 49,732,152
-----------
7,912,044
```

Explanation:
Start from the rightmost digit and subtract column by column. No borrowing is needed here since each digit in the top number is greater than or equal to the corresponding digit below.

2. 858,074 – 674,720

```
858,074
- 674,720
--------
183,354
```

Explanation:
Subtract each column:
- 4 - 0 = 4
- 7 - 2 = 5
- 0 - 7 → need to borrow: 10 - 7 = 3 (borrowed from next)
- 8 becomes 7 after borrow; 7 - 4 = 3
- 5 - 7 → borrow: 15 - 7 = 8
- 8 becomes 7; 7 - 6 = 1

So, result is 183,354

3. 7,833,285 – 850,909

```
7,833,285
- 850,909
----------
6,982,376
```

Explanation:
Align the numbers:

```
7,833,285
- 850,909
----------
```

We can think of it as:

```
7,833,285
- 850,909
----------
6,982,376
```

Work column by column with borrowing where needed. The subtraction gives us 6,982,376

4. 22,647 – 17,906

```
22,647
- 17,906
--------
4,741
```

Explanation:
- 7 - 6 = 1
- 4 - 0 = 4
- 6 - 9 → borrow: 16 - 9 = 7 (borrow from 2)
- 2 becomes 1; 1 - 7 → borrow: 11 - 7 = 4
- 2 becomes 1; 1 - 1 = 0

Result: 4,741

5. 6,134,175 – 624,228

```
6,134,175
- 624,228
----------
5,509,947
```

Explanation:
Subtract column by column. Borrowing occurs in some places, especially in the thousands and ten-thousands.

Final answer: 5,509,947

6. 94,101,219 – 39,009,017

```
94,101,219
- 39,009,017
------------
55,092,202
```

Explanation:
Column-wise subtraction:

- 9 - 7 = 2
- 1 - 1 = 0
- 2 - 0 = 2
- 1 - 9 → borrow: 11 - 9 = 2 (borrow from 0, which borrows from 1)
- Continue carefully...

Final result: 55,092,202

7. 334,084 – 81,100

```
334,084
- 81,100
---------
252,984
```

Explanation:
Subtract directly:
- 4 - 0 = 4
- 8 - 0 = 8
- 0 - 1 → borrow: 10 - 1 = 9
- 3 becomes 2; 2 - 1 = 1
- 3 - 8 → borrow: 13 - 8 = 5
- 3 becomes 2; 2 - 0 = 2

Answer: 252,984

8. 95,561,655 – 64,142

```
95,561,655
- 64,142
-------------
95,497,513
```

Explanation:
Align the smaller number under the larger one:

```
95,561,655
- 64,142
-------------
```

Subtract from right:
- 5 - 2 = 3
- 5 - 4 = 1
- 6 - 1 = 5
- 1 - 6 → borrow: 11 - 6 = 5 (borrow from 6)
- 6 becomes 5; 5 - 4 = 1
- 5 - 0 = 5
- 5 - 0 = 5
- 9 - 0 = 9

Answer: 95,497,513

9. 81,835,443 – 4,916,527

```
81,835,443
- 4,916,527
------------
76,918,916
```

Explanation:
Careful column subtraction. Borrowing may be required in multiple digits.

Result: 76,918,916

10. 26,031,139 – 81,399

```
26,031,139
- 81,399
------------
25,949,740
```

Explanation:
Align:
```
26,031,139
- 81,399
------------
```

Subtract:
- 9 - 9 = 0
- 3 - 9 → borrow: 13 - 9 = 4
- 1 becomes 0; 0 - 3 → borrow: 10 - 3 = 7
- 1 becomes 0; 0 - 1 → borrow: 10 - 1 = 9
- 3 becomes 2; 2 - 8 → borrow: 12 - 8 = 4
- 0 becomes 9 (after borrow); 9 - 0 = 9
- 6 - 0 = 6
- 2 - 0 = 2

Wait — let’s do this more clearly:

Actually:

```
26,031,139
- 81,399
------------
```

We are subtracting 81,399 from 26,031,139.

So:

- Units: 9 - 9 = 0
- Tens: 3 - 9 → borrow: 13 - 9 = 4, carry over
- Hundreds: 1 becomes 0; 0 - 3 → borrow: 10 - 3 = 7
- Thousands: 1 becomes 0; 0 - 1 → borrow: 10 - 1 = 9
- Ten thousands: 3 becomes 2; 2 - 8 → borrow: 12 - 8 = 4
- Hundred thousands: 0 becomes 9; 9 - 0 = 9
- Millions: 6 - 0 = 6
- Ten millions: 2 - 0 = 2

But wait: original number is 26,031,139 → digits:

- 2 (ten millions), 6 (millions), 0 (hundred thousands), 3 (ten thousands), 1 (thousands), 1 (hundreds), 3 (tens), 9 (units)

Subtract 81,399 → which is 081,399 → so:

```
26,031,139
- 81,399
------------
```

Now align:

```
26,031,139
- 81,399
------------
```

So:

```
26,031,139
- 81,399
-----------
```

We subtract from the last five digits.

Start from right:

- 9 - 9 = 0
- 3 - 9 → borrow → 13 - 9 = 4 → tens digit becomes 2 (from 3) → but we already used it?

Better way:

Break down:

26,031,139
– 81,399
= ?

We can compute:

26,031,139 – 80,000 = 25,951,139
Then subtract 1,399: 25,951,139 – 1,399 = 25,949,740

Yes! So final answer: 25,949,740
