8. Multiples of 10 When multiplying by multiples of 10, multiply the number times 1 then add a 0 to the product. Example: 3 x 40= 120 Breaking it down 3 x 4 =12 3 x 40 = 12 + one 0 = 120 When multiplying by multiples of 10, multiply the number times 1 then add a 0 to the product. Example: 3 x 40= 120 Breaking it down 3 x 4 =12 3 x 40 = 12 + one 0 = 120

9. Multiples of 100 When multiplying by multiples of 100, multiply the number times 1 then add two 0s to the product. Example: 3 x 400= 1200 Breaking it down Breaking it down 3 x 4 =12 3 x 400 = 12 + two 0s = 1200

10. Multiples of 1,000 When multiplying by multiples of 1,000, multiply the number times 1 then add three 0s to the product. Example: 3 x 4000= 12000 Breaking it down Breaking it down 3 x 4 =12 3 x 4000 = 12 + three 0s = 12000
