1) 52 × 24

Grid:
- Top row: 50 and 2
- Left column: 20 and 4

Multiply:
- 20 × 50 = 1000
- 20 × 2 = 40
- 4 × 50 = 200
- 4 × 2 = 8

Add: 1000 + 40 + 200 + 8 = 1248

→ 52 × 24 = 1248

2) 35 × 56

Grid:
- Top: 30, 5
- Left: 50, 6

Multiply:
- 50 × 30 = 1500
- 50 × 5 = 250
- 6 × 30 = 180
- 6 × 5 = 30

Add: 1500 + 250 = 1750; 1750 + 180 = 1930; 1930 + 30 = 1960

→ 35 × 56 = 1960

3) 36 × 71

Grid:
- Top: 30, 6
- Left: 70, 1

Multiply:
- 70 × 30 = 2100
- 70 × 6 = 420
- 1 × 30 = 30
- 1 × 6 = 6

Add: 2100 + 420 = 2520; 2520 + 30 = 2550; 2550 + 6 = 2556

→ 36 × 71 = 2556

4) 96 × 42

Grid:
- Top: 90, 6
- Left: 40, 2

Multiply:
- 40 × 90 = 3600
- 40 × 6 = 240
- 2 × 90 = 180
- 2 × 6 = 12

Add: 3600 + 240 = 3840; 3840 + 180 = 4020; 4020 + 12 = 4032

→ 96 × 42 = 4032

5) 84 × 59

Grid:
- Top: 80, 4
- Left: 50, 9

Multiply:
- 50 × 80 = 4000
- 50 × 4 = 200
- 9 × 80 = 720
- 9 × 4 = 36

Add: 4000 + 200 = 4200; 4200 + 720 = 4920; 4920 + 36 = 4956

→ 84 × 59 = 4956

6) 25 × 88

Grid:
- Top: 20, 5
- Left: 80, 8

Multiply:
- 80 × 20 = 1600
- 80 × 5 = 400
- 8 × 20 = 160
- 8 × 5 = 40

Add: 1600 + 400 = 2000; 2000 + 160 = 2160; 2160 + 40 = 2200

→ 25 × 88 = 2200

7) 82 × 59

Grid:
- Top: 80, 2
- Left: 50, 9

Multiply:
- 50 × 80 = 4000
- 50 × 2 = 100
- 9 × 80 = 720
- 9 × 2 = 18

Add: 4000 + 100 = 4100; 4100 + 720 = 4820; 4820 + 18 = 4838

→ 82 × 59 = 4838

---

8) 74 × 98

Grid:
- Top: 70, 4
- Left: 90, 8

Multiply:
- 90 × 70 = 6300
- 90 × 4 = 360
- 8 × 70 = 560
- 8 × 4 = 32

Add: 6300 + 360 = 6660; 6660 + 560 = 7220; 7220 + 32 = 7252

→ 74 × 98 = 7252

---

9) 92 × 19

Grid:
- Top: 90, 2
- Left: 10, 9

Multiply:
- 10 × 90 = 900
- 10 × 2 = 20
- 9 × 90 = 810
- 9 × 2 = 18

Add: 900 + 20 = 920; 920 + 810 = 1730; 1730 + 18 = 1748

→ 92 × 19 = 1748
