Problem 1: 868 × 61

We break 61 into 60 + 1, so:
- Multiply 868 by 1 → 868
- Multiply 868 by 60 → 868 × 6 × 10 = 5208 × 10 = 52,080

Now add:

```
868
× 61
------
868 ← 868 × 1
52080 ← 868 × 60
------
52948
```

✔ Answer: 52,948

Problem 2: 144 × 89

Break 89 into 80 + 9:
- 144 × 9 = 1,296
- 144 × 80 = 144 × 8 × 10 = 1,152 × 10 = 11,520

Add:

```
144
× 89
-----
1296 ← 144 × 9
11520 ← 144 × 80
------
12816
```

✔ Answer: 12,816

Problem 3: 100 × 15

This is easy! Any number times 100 just adds two zeros.

100 × 15 = 1,500

Or:
- 100 × 15 = 100 × (10 + 5) = 1,000 + 500 = 1,500

✔ Answer: 1,500

Problem 4: 749 × 77

Break 77 into 70 + 7:
- 749 × 7 = 5,243
- 749 × 70 = 749 × 7 × 10 = 5,243 × 10 = 52,430

Add:

```
749
× 77
-----
5243 ← 749 × 7
52430 ← 749 × 70
