What is Standard Form?

Standard form (also called scientific notation) is a way of writing very large or very small numbers in a compact format. A number in standard form is expressed as a x 10n, where a (the coefficient) is a number between 1 and 10, and n (the exponent) is an integer.

Examples

Large Numbers

Move the decimal point left until you have a number between 1 and 10.

4,530,000 = 4.53 x 10^6

Small Numbers

Move the decimal point right. The exponent is negative.

0.00045 = 4.5 x 10^(-4)

Numbers Between 1 and 10

Already in standard form with exponent 0.

5.2 = 5.2 x 10^0

How to Convert to Standard Form

  1. Identify the original number (can be positive or negative).
  2. Move the decimal point so the absolute value is between 1 and 10.
  3. Count the number of places you moved the decimal point.
  4. If you moved the decimal left, the exponent is positive.
  5. If you moved the decimal right, the exponent is negative.
  6. Write as a x 10n.

Why Use Standard Form?

  • Makes very large numbers (like the distance to the Sun: 1.496 x 1011 meters) easier to read.
  • Makes very small numbers (like atomic sizes: 1 x 10-10 meters) manageable.
  • Simplifies multiplication and division of extreme numbers.
  • Standard in scientific and engineering fields worldwide.
