Scientific Notation August 27, 2018

What is scientific notation? Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.

What is scientific notation? A number in scientific notation is written as: a•10n where 1≤a<10 (a is between 1 and 10 and may include 1).

What is scientific notation? Examples include: The population of the world is 7 billion people. Standard form: 7,000,000,000 Scientific notation: 7 x109

What is scientific notation? Examples include: The distance from the Earth to the sun is 93 million miles. Standard form: 93,000,000 Scientific notation: 9.3 x107

What is scientific notation? Examples include: The diameter of a grain of sand is 24 ten-thousandths inch. Standard form: .0024 Scientific notation: 2.4 x10-3

What is scientific notation? Examples include: 3.4•105 8.32•10-16 1.0•10150 The first number is between 1 and 10 and may include 1. The exponent may be positive or negative.

What is scientific notation? Examples DO NOT include: -3.2•104 34.0•106  The first number MUST be between 1 and 10 (and may include 1).
