### Scientific Notation

What is scientific notation? notation.

• Scientific notation provides a way to write numbers using powers of ten.

• Written as a product of 2 factors.

• The first factor is a number greater than or equal to one BUT less than ten.

• The second factor is a power of 10.

• 7,500,000,000,000 = 7.5 x 10

**Scientific Notation lets you know the size of a number without having to count the digits!

About 4,200,000 people visit the Statue of Liberty every year. Write this number in scientific notation.
