Example: 3 x 23 = (3 x 20) + (3 x 3) = 60 + 9 = 69

Rewrite the equations using the distributive property and find the answer.

1. 10 × 21 = (10 x 20) + (10 x 1) = 200 + 10 = 210

2. 3 × 12 = (3 x 10) + (3 x 2) = 30 + 6 = 36

3. 8 × 26 = (8 x 20) + (8 x 6) = 160 + 48 = 208

4. 3 × 28 = (3 x 20) + (3 x 8) = 60 + 24 = 84

5. 4 × 23 = (4 x 20) + (4 x 3) = 80 + 12 = 92

6. 5 × 30 = (5 x 20) + (5 x 10) = 100 + 50 = 150

7. 2 × 30 = (2 x 15) + (2 x 15) = 30 + 30 = 60

8. 2 × 23 = (2 x 20) + (2 x 3) = 40 + 6 = 46

9. 4 × 18 = (4 x 10) + (4 x 8) = 40 + 32 = 72

10. 7 × 25 = (7 x 20) + (7 x 5) = 140 + 35 = 157
