What is 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.

  • 4,200,000

  • 4.2

  • 4.2 x 10 ⁶

  • Move the decimal point to get a decimal greater than 1 but less than 10.

  • Drop the zeros after the 2.

  • You moved the decimal point 6 places. The number is large. Use 6 as the exponent of 10.

    • Move the decimal point to get a decimal greater than 1 but less than 10.

  • Drop the zeros before the 7.

  • You moved the decimal point 5 places. The number is small. Use -5 as the exponent of 10.
