Addition Problems

#### 1. $ 996 + 978 $

```
996
+ 978
------
1974
```

- 6 + 8 = 14 → write down 4, carry over 1
- 9 + 7 + 1 (carry) = 17 → write down 7, carry over 1
- 9 + 9 + 1 = 19 → write down 19

✔ Result: 1974

---

#### 2. $ 896 + 968 $

```
896
+ 968
------
1864
```

- 6 + 8 = 14 → write 4, carry 1
- 9 + 6 + 1 = 16 → write 6, carry 1
- 8 + 9 + 1 = 18 → write 18

✔ Result: 1864

---

#### 3. $ 795 + 998 $

```
795
+ 998
------
1793
```

- 5 + 8 = 13 → write 3, carry 1
- 9 + 9 + 1 = 19 → write 9, carry 1
- 7 + 9 + 1 = 17 → write 17

✔ Result: 1793

---

#### 4. $ 598 + 958 $

```
598
+ 958
------
1556
```

- 8 + 8 = 16 → write 6, carry 1
- 9 + 5 + 1 = 15 → write 5, carry 1
- 5 + 9 + 1 = 15 → write 15

✔ Result: 1556

---

#### 5. $ 597 + 938 $

```
597
+ 938
------
1535
```

- 7 + 8 = 15 → write 5, carry 1
- 9 + 3 + 1 = 13 → write 3, carry 1
- 5 + 9 + 1 = 15 → write 15

✔ Result: 1535

---

#### 6. $ 596 + 928 $

```
596
+ 928
------
1524
```

- 6 + 8 = 14 → write 4, carry 1
- 9 + 2 + 1 = 12 → write 2, carry 1
- 5 + 9 + 1 = 15 → write 15

✔ Result: 1524

Subtraction Problems

#### 1. $ 926 - 658 $

```
926
- 658
------
268
```

- 6 - 8 → can't do, borrow: 16 - 8 = 8, 1 borrowed → 1 becomes 0
- 1 (from 2) → now 1, but need to subtract 5 → can't, so borrow from 9 → 11 - 5 = 6
- 8 (after borrowing) - 6 = 2

✔ Result: 268

---

#### 2. $ 835 - 368 $

```
835
- 368
------
467
```

- 5 - 8 → borrow: 15 - 8 = 7, 3 becomes 2
- 2 - 6 → can't, borrow: 12 - 6 = 6, 8 becomes 7
- 7 - 3 = 4

✔ Result: 467

---

#### 3. $ 956 - 598 $

```
956
- 598
------
358
```

- 6 - 8 → borrow: 16 - 8 = 8, 5 becomes 4
- 4 - 9 → can't, borrow: 14 - 9 = 5, 9 becomes 8
- 8 - 5 = 3

✔ Result: 358

---

#### 4. $ 923 - 567 $

```
923
- 567
------
356
```

- 3 - 7 → borrow: 13 - 7 = 6, 2 becomes 1
- 1 - 6 → can't, borrow: 11 - 6 = 5, 9 becomes 8
- 8 - 5 = 3

✔ Result: 356

---

#### 5. $ 753 - 378 $

```
753
- 378
------
375
```

- 3 - 8 → borrow: 13 - 8 = 5, 5 becomes 4
- 4 - 7 → can't, borrow: 14 - 7 = 7, 7 becomes 6
- 6 - 3 = 3

✔ Result: 375

---

#### 6. $ 823 - 386 $

```
823
- 386
------
437
```

- 3 - 6 → borrow: 13 - 6 = 7, 2 becomes 1
- 1 - 8 → can't, borrow: 11 - 8 = 3, 8 becomes 7
- 7 - 3 = 4

✔ Result: 437
