0.000001 = 10^-6 = one millionth

0.001 = 10^-3 = one thousandth

0.1 = 10^-1 = one tenth

1.0 = 10⁺⁰

10 = 10⁺¹

100 = 10⁺²

1000 = 10⁺³ = one thousand

1,000,000 = 10⁺⁶ = one million

1,000,000,000 = 10⁺⁹ = one billion

1,000,000,000,000 = 10⁺¹² = one trillion

Working with Scientific Notation:

One million equals a thousand thousands

or

1000 x 1000 = 10⁺³ x 10⁺³ = 10⁺⁶
